Unprinted C-flute starch-glued regular slotted corrugated boxes

1. Scope and Applicability

This PCR covers one box construction: an unprinted, uncoated C-flute single-wall regular slotted case, FEFCO 0201-G, made from purchased corrugated sheets with an aqueous natural-starch manufacturer joint. The net product is supplied glued and flat, ready for downstream erection; filling and top/bottom flap sealing are outside the foreground. FEFCO distinguishes sheet plants, box plants and integrated plants and explicitly allows converting without printing. [fefco-box-production; fefco-code-2022]

The foreground uses electric slotting/scoring, folding/gluing and conditioning without combustion or purchased steam/heat; rinse is exported for external treatment. Corrugation, pulp/base-paper production, printing, coatings, laminating, stitching, hot melts, synthetic joint binders, solid-board folding cartons, die-cut styles, office articles and other 32153 products are excluded. Any actual excluded operation requires a completed scope/method/inventory extension before use. Ink/varnish absence must be demonstrated by order and issue records: the recycling original treats ink as a formulated material with colorants, resin, carrier and additives, so an unknown printing route cannot be assigned zero. Adhesive guidance supports starch as one box-making choice, not a dosage or a guarantee of no emissions. [fefco-box-production; fefco-recyclability-2025]

Required qualifiers	0201-G drawing/dimensions; single-wall C flute; unprinted/uncoated status; grade/fibre fractions; compatibility with selected 16.6% primary/83.4% recycled total-fibre identity; actual board fibre >=80% and recycled content; adhesive supplied wet/dry state/solids/additives; net mass/gate moisture/packaging tare; glue-joint order acceptance; factory/period/electric supply/delivery point; wastewater receiver; upstream boundaries

Required qualifiers belong in the completed data package. The reference is 1 kg net gate-moist box, not 1 kg oven-dry fibre and not one assumed-weight box. Verify identity restrictions separately from supplier dataset quantity/technology compatibility. The reference record fractions are not a production recipe or environmental-burden allocation; unknown compatibility blocks completed dataset acceptance.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Q is same-period calibrated accepted net box output in kg after bundle tare and rejects, including gate moisture and retained joint solids; Q must be positive. All rows use per reference flow.
moisture_state	board/glue/product/residues	Mass	kg	Keep supplied wet mass, measured solids/water and actual volatile applicability separately. Adhesive wet mass is not dry starch mass.
electric_units	electricity_in	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Use actual delivered electrical energy: verified energy-unit relation is 1 kWh = 3.6 MJ. Do not derive steam heat or combustion efficiency.
water_volume	water_in	Volume 93a60a56-a3c8-22da-a746-0800200c9a66	m3	Meter added water volume. Convert for the separate physical water ledger using sampled density and temperature, not database assumed density.
particle_bins	outdoor air releases	Mass	kg	PM2.5, >2.5 to 10 and >10 are exclusive measured aerodynamic bins. Compatible cumulative differences are allowed; unknown splits remain pending and collected dust is separate.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased unprinted uncoated C-flute sheets and ready aqueous starch adhesive received at converter
starting_condition_role	Gate-to-gate box-converting start; upstream production burdens remain required
product_classification_scope	The restricted RSC subset of CPC 32153, separate from 32151 sheet manufacture
recursive_input_rule	Internal reuse does not cross the boundary. Purchased same-category boxes for repacking are distinct measured inputs with supplier cut point, never a silent deduction or second reference output.
upstream_dataset_requirement	Each sheet background includes actual liner/fluting manufacture, corrugation, embedded flute adhesive and utilities once; joint adhesive supply and purchased utilities need compatible reference bases. Declare transport coverage/endpoints and add individual uncovered transport exchanges.
disclosure	Actual site, period, sources, moisture, foreground electric route, supplier cut points, packing components, receivers and unresolved bases; inherited examples are not measurements

rule_id	applies_to	rule	source_ids
boundary_sheet_box	converter	Begin at sheet receipt. Include slotting/scoring, folding, wet joint gluing, conditioning, acceptance, dust capture, cleaning and gate bundling with all attributable utilities.	fefco-box-production; fefco-code-2022
boundary_upstream	board_in	Supplier pulp/papermaking/corrugation and embedded starch are included once in upstream sheets, not reinjected as converter inputs; do not substitute flat-layer board or corrugator-only results for finished boxes.	fefco-box-production
boundary_ink	product	Demonstrate no print/varnish from order, inspection and chemical issues. Printed, coated or laminated variants require explicit ink/plate/cleaner/waste/species and utility methods before use. Starch glue or water-based ink labels do not demonstrate zero air release.	fefco-box-production; fefco-recyclability-2025
boundary_residuals	converter	Export rinse for external treatment; no on-site biological treatment or combustion occurs in this route. If found, reassess scope and include actual species, including biogenic CO2, instead of assuming zero from GHG reporting convention. No pulper means exported trim is not internally recycled mill broke.	ec-paper-bref-2015

6. Process Inventory Structure

Process Map

box_converter	Sheet-to-flat-box converting and gate bundling	required	The declared electric unprinted C-flute 0201-G starch-joint route	foreground	1 kg reference flow

A single foreground unit aggregates actual transfers of the same box between slotting, joint formation and bundling. Keep stage meters and unallocated physical mass/water/carbon diagrams; every retained internal link must carry equal amounts at both ends. There is exactly one finished reference output. Add each actual extra packaging, lubricant, chemical, transport or utility exchange individually before dataset completion; the finite inventory does not certify every factory configuration.

Inputs

Product flows

Received C-flute single-wall sheets (board_in)

Two unprinted uncoated liners enclose one C-fluted medium. Collect each grade, fibre origin, received moisture, sheet mass and upstream corrugator dataset. This flow requires C/E/F construction, fibre at least 80% and recycled material; this PCR uses only C flute and does not infer any generic furnish. Corrugator starch, liner/fluting manufacture and supplier drying are already upstream.

Purchased aqueous starch joint adhesive (glue_in)

Purchased ready-to-use aqueous natural-starch formulation is applied to the manufacturer joint. Record supplied wet mass, solids, starch origin/modification, additives, SDS and background wet/dry reference. Do not also input its carrier water or upstream ingredients; extra on-site dilution water is separate. Glue consumption and VOC absence are never inferred from the database or recycling guidance.

Added dilution and cleaning tap water (water_in)

Meter actual external additions in m3. Supplied glue water and internal recirculation are not added again. Verify supplier delivery and treatment boundary, geography and reference volume; the located Hong Kong supply record is not a universal background.

The selected source is CN grid-average alternating current below 1 kV at the user; verify actual country, year, supplier mix, transformer losses and delivery point before provider linkage. Convert metered kWh to MJ using the verified energy unit group; Net calorific value is the actual database property, not a steam-enthalpy basis.

Bundle strapping (strap_in)

Record only actual PP strapping issued for flat-box bundles; verify polymer grade, additives, width and mass. Resin, yarn, farm-gate twine and nylon cable ties are not verified strapping identities.

Accepted flat glued box (box_out)

One unprinted uncoated C-flute single-wall FEFCO 0201-G structure, with a glued manufacturer joint and top/bottom outer flaps meeting centrally on erection; supplied flat, before filling and flap sealing. Net accepted mass includes retained joint solids and gate moisture, excludes bundle packaging and rejects. The selected reference record contains 16.6% primary and 83.4% recycled fibre: verify actual total-fibre split and provider basis before using this UUID in a completed dataset; these are identity compatibility conditions, not a factory recipe, an allocation share or a consumption default. Incompatible products require another verified reference identity, never silent widening.

Strapping physically dispatched with boxes (strap_dispatch)

Record the full actual PP strapping mass crossing the gate with accepted flat-box bundles, separately from net box mass, strapping offcuts and stock changes. Reconcile issued strap = dispatched strap + actual offcuts/losses + stock increase, with returns counted once. This is accompanying packaging, not another box function or co-product. Its physical output does not cancel the purchased strapping burden or create recycling credit; burden allocation cannot shrink physical dispatched mass. Finished PP-strapping identity remains unresolved; neither adhesive BOPP tape nor metal bands or coated steel rope represent it.

Waste flows

Exported corrugated trim and rejected boxes (trim_out)

The broad paper/paperboard-waste identity conditionally includes the measured unprinted corrugated trim and rejected boxes; retain specific C-flute composition, joint-starch contamination, moisture and receiver acceptance. Weigh this separately from collected fine dust. Converter has no pulper: shipment for recycling is external waste, not internal mill broke and not an automatic recovered-product credit.

Captured paper dust (dust_out)

Weigh actual captured industrial paper-cutting dust separately, retaining cellulose, filler and starch content, moisture, collector opening/closing stock and actual receiver. This is a Waste flow for collected dust, not kiln ash or an atmospheric particle interval. Internal return is not exported; do not subtract the same captured mass again from measured post-control emissions. No collection efficiency or treatment route is preset.

Exported cleaning effluent (effluent_out)

Keep actual separately collected untreated aqueous joint-equipment wash liquid distinct from concentrated discarded glue. Measure whole-mixture wet kg directly or as measured V_eff*rho_eff(T), not pure-water kg or assumed water density. Retain starch, additives, solids/COD where relevant, actual water fraction and receiving-treatment requirements. Pollutant loads use measured whole effluent volume. External treatment is linked once; this transfer is not also a direct aquatic water/pollutant release or a second purchased water supply. Broad liquid-waste identity prescribes no hazard classification or treatment route.

Separate discarded joint glue (glue_waste_out)

Weigh the actual separately collected liquid spoiled or unused aqueous starch joint glue in its whole wet supplied form. Record starch, other solids/additives, water fraction, packaging separation and the actual receiver. Dried, gelled or solidified residues require separate applicable identities and physical rows. Exclude glue already in rinse or rejected boxes. This liquid-waste identity is not a default hazardous designation, wafer-production residue, recovery yield or disposal technology.

PP strapping offcuts sent for recycling (strap_waste_out)

This PP waste identity has CAS 9003-07-0 and a mechanical-recycling route; use only for separately collected actual PP strapping offcuts accepted by that receiver. Mixed polymer, contaminated waste or another disposal route needs another compatible identity. Neither downstream recycling yield nor lifespan in its comment is a foreground default.

No universal service life, maintenance kit or replacement rate is assumed.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_hierarchy	shared units	Prefer measured subdivision; investigate system expansion consistently with study scope; when allocation is necessary justify relevant physical relations before other relations such as economic allocation, and retain sensitivity. No universal share.	eu-pef-allocation-2021
allocation_physical	physical and burden ledgers	Preserve actual gross product, waste, water and carbon quantities and equal internal links in a physical ledger. Apply allocation only in a separate environmental-burden ledger; never multiply physical co-product output by a burden share.	eu-pef-allocation-2021
allocation_waste	trim_out; strap_waste_out	Positive waste value alone does not establish a co-product. Retain material state, actual receiver/continuing use and waste or product decision. No automatic avoided-paper/plastic credit or second upstream charge for internal returns; any broader recycling method needs separately disclosed assumptions.	eu-pef-allocation-2021

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_exchange	all non-reference rows	q_i = A_i / Q; A_i is the same-period external exchange total in its row unit; Q is accepted net gate-moist box kg.	cp_mass; cp_board; cp_glue; cp_energy; cp_pack; cp_waste; cp_air; cp_water	row amount per reference flow
electricity_mj	electricity_in	A_MJ = 3.6 * A_kWh; verified energy-unit conversion, metered at the declared delivery point.	cp_energy	MJ per reference flow
solids_water	board/glue/box/wastes	m_solid = m_wet * s; m_water = m_wet * (1-s); s is measured solids mass fraction with method/volatile applicability checked. Keep gate-moist reference mass unchanged.	cp_mass; cp_board; cp_glue; cp_waste; cp_water	separate physical solids and water
whole_liquid_mass	effluent_out; glue_waste_out	A_wet_kg = V_m3rho_mixture(T), or direct calibrated whole-wet weighing. Water-component mass = A_wet_kgx_water; retain actual solids/other constituents and whole effluent volume for pollutant loads. Divide by the same Q once.	cp_water; cp_waste; cp_mass	kg per reference flow and separate physical water balance
physical_balance	box_converter	For solids, water and carbon separately: inputs = net product + accompanying packaging dispatched + exported waste + environmental release + stock change; equal internal links cancel. Water mass = volume * measured density. Measure carbon content and origin; no generic carbon fraction or CO2 factor.	cp_mass; cp_board; cp_glue; cp_pack; cp_water; cp_waste; cp_air	unallocated physical ledger and residual
pm_exclusive	pm25_out; pmcoarse_out; pmover10_out	PM2.5-10 = matched cumulative PM10 - PM2.5; >10 = comparable total particulate - PM10. Only compatible definitions/conditions/detection limits allow subtraction; investigate negative differences; otherwise measure the exclusive bin.	cp_air	exclusive kg per reference flow

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
identity	all rows	Verify full multilingual name, species/CAS when relevant, material form, hard route, medium/submedium, classification and property/unit; physical identity does not prove provider quantity compatibility.	supplier records; direct flow/property/unit records
measurement	all protocols	Use matched actual site/period, calibrated measurement and uncertainties. Missing quantities, unknown receiver/particle split or compatibility are pending, never default zero or inherited recipe.	cp_mass; cp_board; cp_glue; cp_energy; cp_pack; cp_waste; cp_air; cp_water
emission_coverage	actual route	Screen dust, retained adhesives/additives and actual utility/waste facilities. Add every relevant atomic species before completion; preserve biogenic CO2 when actually present even if a GHG account treats it differently. No assumed incineration/biological loss occurs inside the declared route.	cp_air; cp_glue; cp_energy; cp_waste; actual site diagram

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_scope	product	Verify 0201-G geometry, single-wall C flute, absent printing/coating and actual wet starch joint; classification name cannot establish method applicability.	fefco-code-2022; fefco-box-production
validate_reference	box_out	Exactly one product output is linked by box_out or the reference UUID; it is 1 kg net gate-moist box. Verify record fibre restrictions and background compatibility before complete dataset acceptance.
validate_boundary	box_converter	Upstream corrugation/embedded glue and converter joint glue are distinct; prove no overlapping manufacture or utilities and no direct-water emission double count for exported rinse.	fefco-box-production; fefco-recyclability-2025
validate_physical	all rows	Every protocol and quantity uses the same positive Q and per reference flow. Review mass/water/carbon residuals and equal internal links before a separate allocation ledger.	eu-pef-allocation-2021
validate_air	particle and vapour rows	Three particle bins are exclusive and separate from captured dust; do not add cumulative totals. Missing source/species measurements or unexplained water residuals prevent complete acceptance; no zero inferred from unprinted or starch labels.	ec-paper-bref-2015
validate_completeness	dataset	Resolve or explicitly review blank UUIDs, actual added packing/chemicals/transport and provider bases before calling a dataset complete. Guidance identity is not measurement evidence, scientific approval or product certification.

10. Published Dataset Profile

downstream_use	Compatible empty flat-box input to product-packing models; upstream sheet dataset remains separate
allowed_use	Only actual within-scope boxes with completed inventory, identity and quantity compatibility
excluded_use	All CPC 32153 coverage; printed/solid-board/die-cut containers; filled package service comparison; unknown fibre/provider bases
required_metadata	Structure/drawing, dimensions, grade/fibre split, net mass/moisture, joint formulation, gate state, supplier cut points, place/period/utilities, receivers and transport
required_quality_disclosure	Measurement/identity gaps, provider bases, calibration, particle coverage, balances/residuals, allocation, uncertainty and review state
update_trigger	Change in structure/board/glue/printing, supplier/energy/effluent route, packaging, period or material source
