PRACTICAL READING PATHS
From one packaging question to a practical next step.
Four complete Chinese–English guides connect material choices, industry resources and editable working tools. Explore the wider 101-application map whenever you need it.
- 01
Hot beverage paper cups: leaks, material selection and whole-cup validation
Connect the first leak to body and bottom stock, sealing, industry resources and trial records, then make a reviewable stage decision.
- 02
Food paper bags: grease marks, moisture and bag-making reliability
Use bakery retail bags to connect food condition, grease-resistant paper, folds and glue lines, industry resources and complete delivery.
- 03
Paper-based food flexibles: structures, seals and product protection
Match confectionery, chocolate, snacks, coffee, tea and seasonings to the right paper, functional layers, converting partners and complete-pack trial.
- 04
Water-based barrier paper and PHA coatings: from material to finished pack
Connect coating chemistry, paper specifications, drying and converting with material suppliers, coaters and cup, bag and flexible-packaging applications.
Four complete bilingual working guides cover cups, bags, food flexible packaging and waterborne paper, with bilingual worksheets. The wider application studies and some source records remain in Chinese and are labelled accordingly.
