Baofeng outlines kraft paper box spec with PLA coating and foldable design

Wenzhou Baofeng Packaging Technology Co., Ltd. has published technical details for its BF-PB-003 disposable takeaway paper box, including kraft board, PLA coating and a foldable structure. The specification and compliance claims matter as buyers face tighter packaging rules in Europe and the U.S. and look for food-contact packaging that balances barrier performance, certification and custom branding.

Why it matters: - The BF-PB-003 sits in a fast-growing food packaging category where board choice, coating chemistry and fold accuracy can determine whether a box passes buyer qualification. - The product is aimed at takeaway, delivery, bakery, fast food, catering, prepared meals and supermarket retail uses. - Tightening rules in the European Union and the United States make coating and compliance part of the product decision, not an afterthought.

What happened: - Wenzhou Baofeng Packaging Technology Co., Ltd. published a technical review for its disposable takeaway paper box, model BF-PB-003. - The company lists the box as a compostable food paper box and custom printed takeaway box. - The specification names food-grade kraft paper with PLA coating as the material set. - The listed board weight range is 230gsm to 400gsm. - The box is foldable and can be supplied with or without a window. - Custom logo and design printing are available. - The listed certifications are FDA, BRC and FSC compliant. - The declared features include microwave safe, compostable, leak-proof and grease-resistant performance.

The details: - The published sizes are customizable by length, width and height. - The reference formats listed are 15×10×5 cm and 20×15×8 cm. - The coating is described as grease-proof and water-proof. - The product is presented as a folding kraft-board box, not a corrugated box. - No flute profile, single-wall or double-wall specification is listed. - Strength is therefore tied to board weight, panel geometry and coating, not to a corrugated medium. - Higher board weight generally increases stiffness and resistance to compression and puncture. - Lower board weight generally reduces material use and cost. - The specification does not publish a load-bearing, stacking or compression rating. - Usable load capacity depends on board weight, panel dimensions, fold and glue configuration, and how contents are distributed. - A deeper box with large unsupported panels will flex earlier than a shallow box of the same board weight. - Buyers needing a defined load figure would normally validate it with a filled, assembled sample. - PLA is a biobased and compostable polyester used in food-service fiber packaging as an alternative to conventional polyethylene coatings. - The published data does not list a numeric water-resistance grade, barrier rating or coating weight. - Moisture and grease performance usually depends on coating type and applied coating weight rather than a single index number. - One listed application pairs the box with a retail-chain ice cream and dessert program requiring compostable material and AS5810 compliance. - Another listed application is a restaurant-chain takeaway program requiring grease-proof and microwave-safe performance. - A third covers cold and hot drink service for chain stores, with food-grade, leak-proof and custom-logo requirements. - One scenario pairs the BF-PB-003 with the company's BF-PC-001 paper cup, listed at 4oz to 20oz, 190gsm to 350gsm, with PLA or PE coating and temperature resistance from -20°C to 100°C. - The box is supplied as a die-cut, foldable structure with an optional window. - The published data does not include die-cutting tolerances, crease accuracy figures or glue-joint specifications. - The specification also does not define window dimensions or film material. - Printing is available with a custom logo or design, which supports branded takeaway boxes. - Baofeng states that it holds BRC, BSCI, FSC Forest Certification, ISO 9001 and ISO 14001 certifications. - Baofeng also states that its products meet multiple international testing standards, including U.S. FDA requirements. - The BF-PB-003 data specifically lists FDA, BRC and FSC compliance. - The company says it has led the drafting of three national standards and two group association standards. - Baofeng says it is a national high-tech enterprise, a Zhejiang Province Specialized, Refined, Differential and Innovative SME, and a Zhejiang Provincial Export Brand Enterprise. - The company was founded in 1996 and is based in Longgang, Wenzhou, Zhejiang Province. - Baofeng says it has more than 200 employees, modern standard workshops and more than 100 production machines. - The company says it has a professional R&D team of 50 people. - Main products include paper cups, paper boxes, paper bags, paper plates and paper bowls. - Stated output is about 8 million pieces per day and nearly 3 billion pieces per year. - The company reports annual output value above RMB 300 million. - Baofeng says export sales account for 80% of its business. - The company lists the United States, the European Union, Canada, Australia, the United Kingdom, Dubai, Qatar, South Africa, Singapore, Japan and South Korea among its markets. - Baofeng says it exports to more than 100 countries. - The company offers one-stop ODM and OEM services covering design, development and manufacturing. - Brands listed as OEM customers include China Eastern Airlines, China Southern Airlines, Juneyao Airlines, Loong Air, Shenzhen Airlines, Atour Hotel, China Resources Group, Wanda Cinemas and Yonghui Supermarkets.

Between the lines: - The specification answers material, coating, board weight and structure, but leaves performance-critical details open until a sample or batch document is reviewed. - That split is typical in food packaging, where product sheets often define construction while order-specific documents define test results. - Certification helps establish market access, but it does not show how a finished box will perform in a specific filling line or end-use scenario. - The regulatory direction in the EU and U.S. increases pressure on coated fiber packaging suppliers to document materials and food-contact compliance more clearly. - Published market data suggests demand for paper lunch boxes and kraft food packaging is still expanding, which keeps pressure on converters to balance cost, barrier and sustainability claims.

What's next: - Buyers are likely to ask for filled-box testing, migration reports and batch-specific documentation before approving the BF-PB-003 for production use. - The key unresolved points are load capacity, barrier duration and dimensional tolerance. - In this category, those details usually decide whether a custom takeaway box makes it onto a filled-goods line.

The bottom line: - Baofeng’s BF-PB-003 is positioned as a food-contact kraft box with PLA coating, custom printing and export-market certifications. - The product sheet gives buyers the material framework, but not the finished-performance data they still need to sign off on real-world use.
