FIBER SUBSTRATE ATLAS

Fiber base material map

As the basis for engineering route screening, material selection starts from fiber structure, paper surface, pores, processing window and complete packaging risks.

Material map:The page focuses on food and beverages, beauty and personal care, medicine and medical care, and special paper-based packaging, organizing material classification, retrieval and passport fields; brand names, supplier data and performance data are entered into the project data layer management.

Enter by material category and then narrow the scope based on real conditions.

The seven-category material framework establishes a unified language; specific recommendations still need to go back to paper patterns, contents, processing equipment, target markets and complete packaging testing.

7 categories of materials have been displayed. You can continue to filter by name, alias, use and risk.

BT-PB-BOARD
CLASS / 01

Food packaging cardboard

Cupstock / FBB / SBS / SBB / LPB

This is an application category, not a single standard grade. It is necessary to continue to distinguish according to fiber layer, basis weight, bulk, stiffness, Cobb, paint retention, indentation and forming ability.

Main risksPaint penetration, crease cracking, edge cutting and liquid absorption, heat sealing and anchoringRecommend verificationPaper characterization, planar blocking, creases, trimming and complete productsVerification key pointsSpecific paper pattern, grade and batch
BT-FP-THIN
CLASS / 02

Flexible packaging tissue paper

Greaseproof / Glassine / Flexible Base Paper

Maintain continuous coating, mechanical strength, sealing performance and high-speed packaging adaptability at lower material usage. Dense greaseproof paper, cellophane, single-sided glossy and special coated base paper should be distinguished.

Main risksPinholes, curling, flex cracks, insufficient tension and wet strengthRecommend verificationBreathable, tearable, coating retention, barrier and paper feeding after bendingVerification key pointsRoll status and paper transport window
BT-KR-KRAFT
CLASS / 03

Kraft paper

Bleached / Unbleached / MG / Extensible Kraft

Kraft paper is first and foremost a pulping and fiber performance system and is not a synonym for brown paper. Bleaching status, fiber source, surface treatment, strength and intended use need to be stated.

Main risksHigh pores, rough paper surface, lifted fibers, odor and uneven coatingRecommend verificationSealing primer, surface energy, coating amount, ink absorption and odorVerification key pointsColor, odor and food contact pathways
BT-NF-FIBER
CLASS / 04

Bamboo pulp and non-wood fiber paper

Bamboo / Bagasse / Other Non-wood Fiber

The material passport simultaneously records the actual fiber proportion, blending, pulping route, bleaching, auxiliaries, supply chain information and related performance and compliance information.

Main risksUnclear proportion of raw materials, extrapolation of performance, and lack of boundaries in environmental statementsRecommend verificationFiber composition, paper properties, food contact and actual terminal pathdeclare boundariesDon’t use default conclusions such as “natural is more environmentally friendly”
BT-MF-MOLDED
CLASS / 05

Pulp molding

Wet Press / Thermoformed Fiber / Dry Formed Fiber

Distinguished by molding process, surface quality, structural accuracy and functional layer. The barrier evaluation object should be the complete molded part, not the flat paper piece with the same formula.

Main risksConcave corners, flanges, ribs, density differences, coating accumulation and dimensional changesRecommend verificationComplete molded parts, cover film sealing surface, stacking, demoulding and moisture absorptionVerification key pointsMolding process and size window
BT-ST-BOARD
CLASS / 06

Corrugated base paper and structural paperboard

Containerboard / Structural Board

For transportation, cushioning and high-strength structures, barrier function must be evaluated together with compression, puncture, heat and moisture, bonding, printing and logistics conditions.

Main risksHigh wet strength loss, interlayer adhesion, local crushing and coating brittlenessRecommend verificationWet resistance to pressure, puncture, adhesion, impact vibration and environmental agingVerification key pointsTransport conditions and structural grade
BT-SP-SPECIAL
CLASS / 07

Medical paper and high-performance specialty paper

Medical Paper / Specialty Functional Paper

General pharmaceutical outer packaging, non-sterile consumable packaging and terminal sterilization medical device packaging must be distinguished according to specific uses. Material name does not automatically prove medical grade.

Main risksUse out of bounds, granules, sealing, peeling, sterilization and process validation gapsRecommend verificationIdentify combinations of standards, materials and process validation by specific project onlyapplicable boundaryThe applicability of ISO 11607 needs to be verified on a project-by-project basis

Each material passport answers four sets of questions.

After the material route enters the project, Plus, Pro, and Ultra are used as candidate solutions; the passport simultaneously records the number, version, review, evidence, permissions, and review date.

Material identity and manufacturing

  • Accurate name and industry alias
  • Fiber source and blending status
  • Virgin or regenerated fiber
  • Pulp and paper machine technology
  • Single or multi-layer structure
  • Fillers, sizing and surface treatments

Performance and inherent limitations

  • Basis, thickness, density and moisture content
  • Tensile, tear, stiffness and folding resistance
  • Cobb, Breathability, Porosity and Roughness
  • Surface energy and coating retention
  • Known failure modes
  • Data methods and test conditions

Processing and packaging adaptation

  • Coating and drying
  • Printing and ink adhesion
  • Die cutting, creasing and folding
  • Cups and bowls, bag making and molding
  • Heat sealing and sealing surface
  • Correlating barrier systems with samples

Safety, circularity and evidence

  • Food contact markets and uses
  • Restricted Substances and Supply Chain Documentation
  • Recycling or composting path status
  • Scope of reports and certificates
  • Disclosure, application or NDA permissions
  • Change record and review date

Comes in with paper pattern and packaging conditions.

Material classification can only narrow the scope. After the pattern, contents, processing equipment and target market are submitted, material selection, coating and testing routes can be established.
