2026年8月12日,欧盟PPWR《包装和包装废弃物法规》将开始普遍适用。这不意味着所有义务在同一天全部落地,却标志着包装减量、循环设计、材料安全和信息透明进入分阶段实施的新周期。
一、PPWR适用在即,包装必须回答五个问题
包装要做减法:重量、体积、空隙和非必要功能层都将受到更严格审视,每一层材料都要说明其功能必要性。
可回收要从设计开始:循环能力不能只看材料名称,还取决于基材、涂层、整体结构和现实再生路径。
食品接触安全要落实到每一层材料:PFAS等物质控制正在走向可检测、可追溯、可说明,基材、功能层、油墨和胶黏剂需要共同进入评价。
绿色概念要各归其位:生物基、可降解、可堆肥和可回收分别对应不同价值与末端路径,不能相互替代。
环境承诺必须可验证:减少了多少材料、纸基占比多高、是否影响纤维循环,都需要具体结构、数据和第三方证据支撑。
PPWR的要求将分阶段实施,部分技术方法和实施细则仍待后续法案进一步明确。到2028年前后,可回收设计方法、材料标签及部分减量要求将陆续细化或强制;而材料筛选、设备适配、制品测试和客户验证都需要时间,未来两年正是企业完成技术转换的重要窗口。
与此同时,欧盟一次性塑料制品指令(SUPD)仍在影响含塑料功能层的一次性纸基包装,低塑料含量不存在当然适用的统一豁免线;国际品牌面向2028年的减塑、循环和碳管理目标,也在加快转化为供应链采购条件。2028年不是行动起点,而是今天选择的材料路线开始接受市场检验的节点。
纸代塑需要的,不是简单增加一层所谓“环保涂层”,而是一层用量更少、能够制造、使用安全,并兼顾包装功能与纤维循环的材料系统。这正是博碳包装希望补上的关键一层。
二、纸代塑缺的不是纸,而是关键功能层
纸张具有强度、印刷适和纤维循环基础,却不会因为被制成杯、碗、盒或袋,就自动具备完整包装功能。
随着全球各地对减塑限塑政策的接连加严,政策大锤真正落下时,传统PE塑料淋膜纸产业必将需要一款好材料来接替,它需要有条件满足源头减量降碳促循环的考核,承接阻隔与加工功能、并支持真实回收再浆路径的好材料。
真正的难点,是让少量功能材料在纸张表面稳定铺展,封闭纤维孔隙并形成连续膜层,同时经受食品接触安全、热封、折叠和成型。阻水、阻油、成膜、热封、耐折、设备适配和成本,必须在同一个项目中回答。
博碳包装由此形成一项共同原则:用尽可能少的功能材料,完成恰到好处的包装功能,并兼顾成本、制造、验证与纸纤维循环。
“少”不是以牺牲性能为代价,而是在明确内容物、使用环境和加工方式之后,只配置目标包装真正需要的功能。
三、一套材料体系,回答三类产业问题
纸张、设备、内容物和市场要求各不相同,纸代塑不可能依靠一款“万能乳液”完成。基于“少而够用”的共同原则,博碳包装形成了由博碳平衡、博碳专业和博碳定制组成的三层产品与工程体系。
博碳平衡,解决长期采用。BiotenPlus 面向主流纸基包装,在满足必要阻隔和加工要求的同时,综合考虑PHA生物基材料用量、制造复杂度、经济性与综合成本,为纸厂真实回收、易再浆、纤维高得率设计,同时适用条件下的堆肥处置留下空间。
产品用得住、产线做得出、客户用得起、使用后回得去,才是规模化替代传统PE塑料淋膜的竞争基础。这与PPWR面向减量、可回收设计和生物基信息验证的长期方向相呼应。
事实上,博碳平衡不是对某一个节点的短期应对,而是把功能必要性、材料用量、制造效率、成本和纤维循环放进同一套产品逻辑。用科学的可预见性产品设计适配全球政策节段性加严的要求和中长期符合的能力。
从而我们更加深刻的理解PPWR在2026年8月适用要求、2028年对数据底线要求、2030年的淘汰条件与2035年的关门要求的结论。
博碳专业,解决专业进入。BiotenPro 这是我们迄今为止市场中可堆肥降解产品要求中最为领先的水性阻隔材料系统,它进一步叠加市场化供应与严格的BPI家庭堆肥认证的一致性,DIN CERTCO、ABA 家庭与商业堆肥适配基础上,市场化供应和第三方材料端证据。
面向对材料组成、制造一致性、认证和文件提出更高要求的市场,把材料路线转化为可采购、可加工、可审查并可继续开展制品验证的专业产品。这是一款在真实产业中能满足热封与性能阻隔使用,又能符合BPI堆肥降解认证及检验要求的市场化产品。
博碳定制,解决边界突破。BiotenUitra 面对食品饮料、美妆个护、医药、电子及特种包装,它根据内容物、货架期、纸张与工艺条件,设计高阻氧、高阻湿、防潮、耐介质或边缘密封等必要组合,拓展通用材料难以覆盖的应用边界。
博碳定制支持与产业链企业联合开发,包括性能边界、生物基含量、专属定制产品与独家合作供应。
由此,Bioten 形成清晰的产品矩阵:博碳平衡解决长期采用,博碳专业解决专业进入,博碳定制解决性能边界突破。
在此基础上,博碳包装水性阻隔工程系统可与细分行业企业开展专属产品定制开发与合作供应。
四、从‘少而够用’到可验证,纸代塑必须走向工程化
低用量是重要的工程方向。在部分典型纸杯纸结构中,若按约10克/平方米干涂布量估算,功能层可能约占整杯质量的3%,纸基约占97%。
这组数字用于理解结构减量,实际比例会随杯型、纸张和结构变化;它不是PPWR、SUPD或堆肥标准中的豁免线,也不能单独证明完整纸杯可回收、可堆肥或符合食品接触要求。这些问题需要水性阻隔材料开发者逐项解决。
博碳包装的价值,不在于用一张证书替代全部判断,而在于把PHA水性阻隔推进为可正式供应、可接受产业链审查,并能支持下游继续完成制品验证的专业产品。
纸代塑也由此从“材料可以替代”的概念,走向可验证、可采购、可持续交付的产业能力。
五、以原创技术支撑产业协同发展,补上纸代塑关键一层
截至2026年8月,都佰城及相关研发主体已公开专利106项,其中56项已获国家知识产权局授权。比数量更重要的是,其中围绕生物基水性化阻隔与PHA基阻隔的授权成果,正形成一条连续的原创技术链、赋能中国造纸与包装企业形成高质量可持续的全球化市场竞争局面。
文中列示了部分代表性发明专利及公开授权编号:1、生物基聚合物乳液及其制备方法与应用 CN121758933B,2、聚羟基脂肪酸酯水性阻隔涂层组合物及应用 CN120925356,3、PHA分散体乳液及其制备方法与应用 CN120757803B,4、基于微生物发酵PHA的生物基低VOC水性油墨组合物及其制备方法、应用和印刷方法 CN121319702B,5、纯生物基PHA水性分散体及其制备方法与用途 CN120865687B,6、汉堡纸用生物基PHA阻油透湿涂料、涂覆纸及制备方法 CN120759147B,7、一种PHA、PBAT与PVOH共混水性乳液及其在纸基阻隔涂层的应用 CN120026524B,8、一种纸基材料用阻隔涂料组合物、阻隔涂层及纸基材 CN119434019B,9、矿物基易回收可堆肥水性阻隔涂层及其制备方法 CN120925354B,10、反应型相容化ACR-PHA核壳乳胶及其应用 CN120944032B。
真正的纸代塑,不是材料企业独自完成的一次替换。从乳液到市场包装,需要原纸、涂布、制品、检测认证和终端品牌共同把基材、工艺、内容物、货架期及目标市场带入项目。
博碳包装希望承担的,正是材料与应用之间的组织角色:把材料选择、加工适配、第三方证据和终端验证连接起来,减少反复试错,让适合的材料更快进入适合的场景。
一款好材料不是纸代塑的全部,却可以成为产业协同的起点。
当低用量功能材料、稳定制造、第三方证据和完整制品验证真正连接起来,纸代塑才能从“有材料可以替代”,走向“有能力持续交付”。
博碳包装要补上的,不只是一层阻水、阻油或热封涂层,更是连接纸张优势与包装功能、原创技术与工业制造、循环方向、堆肥降解路径与市场验证的关键一层。
这正是我们描绘的“纸代塑2.0时代”,它需要从业者们更新认知,建立新基础,企业才能走向全球。
中国拥有庞大且成熟的造纸与包装产业链企业集群,全球有超过3000万吨的纸代塑替换市场,还有减塑禁塑全球持续加严的政策。
我们认为,无论是丙烯酸阻隔乳液、PHA水性阻隔乳液、还是PLA淋膜、或是各种生物基材料阻隔涂层,在纸代塑的高需求市场增长过程中,都必将存在。这时候竞争的是企业的专业能力与经营者的定力,合作创新、协同创新是走向高质量规模化最快捷径,我们一直在努力实现这种多赢局面。
欧洲正在以政策重塑引领全球包装规则,中国则有机会以材料创新与制造能力提供新的答案。政策、技术与市场在此交汇,正在为纸代塑打开一个难得的高质量发展窗口。
博碳包装阻隔系统,期待志同道合的行业伙伴与我们同行,协同开创全球市场,以真正可用、经得起验证、能够被长期采用的产品,把这一窗口转化为产业发展的现实机会。把这件真正有价值的事情做成。

On August 12, 2026, the EU Packaging and Packaging Waste Regulation (PPWR) will generally apply. This does not mean that every obligation takes effect on the same day, but it marks the beginning of a new, phased cycle for packaging minimisation, design for circularity, material safety, and information transparency.
1. As the PPWR Approaches, Packaging Must Answer Five Questions
Packaging must use less: weight, volume, empty space, and unnecessary functional layers will face closer scrutiny, and every material layer must demonstrate its functional necessity.
Recyclability must begin with design: circular performance depends not only on the name of a material, but also on the substrate, coating, overall structure, and realistic recycling route.
Food-contact safety must extend to every material layer: controls on PFAS and other substances are moving toward measurable, traceable, and explainable evidence. Substrates, functional layers, inks, and adhesives must be assessed together.
Environmental concepts must retain their distinct meanings: bio-based, biodegradable, compostable, and recyclable each represent different values and end-of-life routes; none can automatically substitute for another.
Environmental commitments must be verifiable: the amount of material reduced, the proportion of paper fibre, and any effect on fibre circulation all require support from specific structures, data, and third-party evidence.
PPWR requirements will be implemented in stages, and some technical methods and detailed rules remain subject to subsequent legislation. Around 2028, design-for-recycling methods, material labels, and certain minimisation requirements are expected to become more detailed or mandatory. Material screening, equipment adaptation, finished-product testing, and customer validation all take time, making the next two years an important window for technical transition.
At the same time, the EU Single-Use Plastics Directive (SUPD) continues to affect single-use paper packaging that contains a plastic functional layer. A low plastic content does not create an automatic, uniform exemption. International brands are also converting their 2028 plastic-reduction, circularity, and carbon-management goals into supply-chain purchasing requirements. The year 2028 is not the starting point for action; it is when material choices made today begin to face market validation.
Paper-for-plastic packaging does not simply need another so-called “green coating.” It needs a material system that uses less, can be manufactured safely, and balances packaging performance with fibre circulation. This is the critical layer that BIOTEN Packaging aims to provide.
2. Paper-for-Plastic Packaging Does Not Lack Paper; It Lacks the Critical Functional Layer
Paper offers strength, printability, and a foundation for fibre circulation, but turning it into a cup, bowl, carton, or bag does not automatically provide complete packaging performance.
As plastic-reduction and restriction policies tighten worldwide, conventional PE-coated paper will need a capable successor. That material must support source reduction, lower carbon impact, and circularity; provide barrier and processing functions; and enable a realistic repulping route under applicable conditions.
The technical challenge is to spread a small amount of functional material evenly across paper, close the fibre pores, and form a continuous film that can withstand food-contact safety assessment, heat sealing, folding, and converting. Water resistance, oil resistance, film formation, heat sealing, flex resistance, equipment compatibility, and cost must all be addressed within the same project.
BIOTEN Packaging has therefore adopted a shared principle: use the smallest practical amount of functional material to deliver the packaging performance actually required, while considering cost, manufacturing, validation, and fibre circulation.
“Less” does not mean sacrificing performance. It means first defining the contents, use environment, and converting process, and then specifying only the functions the target package genuinely needs.
3. One Material System for Three Types of Industry Challenge
Paper grades, equipment, packaged contents, and market requirements differ. Paper-for-plastic applications cannot be solved by one “universal emulsion.” Based on the common principle of “less, but sufficient,” BIOTEN Packaging has developed a three-tier product and engineering system: BIOTEN Plus, BIOTEN Pro, and BIOTEN Ultra.
BIOTEN Plus supports long-term adoption. For mainstream paper packaging, it balances necessary barrier and converting performance with PHA bio-based material use, manufacturing complexity, economics, and total cost. It is designed to support practical mill recycling, easier repulping, and high fibre yield, while leaving room for composting under applicable conditions.
A product must perform in use, run on production lines, remain commercially accessible, and return to an appropriate recovery route after use. These are the competitive foundations for replacing conventional PE-coated paper at scale, and they align with the PPWR’s long-term direction on minimisation, design for recycling, and verification of bio-based information.
BIOTEN Plus is not a short-term response to a single regulatory milestone. It places functional necessity, material use, manufacturing efficiency, cost, and fibre circulation within one product logic. Its aim is to use scientifically foreseeable product design to respond to progressively stricter global policy and support medium- and long-term compliance capability.
This also helps frame the PPWR timeline: general application in August 2026, emerging data baselines around 2028, phase-out conditions in 2030, and further market-access thresholds in 2035, subject to the regulation and subsequent implementing measures.
BIOTEN Pro supports professional market entry. It is BIOTEN’s advanced water-based barrier material system for applications with compostability requirements. It combines commercial supply with material-level third-party evidence, including the applicable scope of BPI home-compostability certification and alignment work relating to DIN CERTCO and ABA home and commercial compostability programs.
For markets with higher requirements for material composition, manufacturing consistency, certification, and documentation, BIOTEN Pro turns a material route into a professional product that can be purchased, processed, reviewed, and taken forward for finished-product validation. The source article describes a commercially available product designed to provide heat-sealing and barrier performance while supporting applicable BPI compostability certification and testing requirements.
BIOTEN Ultra supports performance-boundary development. For food and beverage, beauty and personal care, pharmaceutical, electronics, and specialty packaging, it designs the necessary combination of high oxygen barrier, high moisture barrier, moisture protection, chemical resistance, or edge sealing according to the contents, shelf life, paper, and process conditions.
BIOTEN Ultra supports joint development with value-chain companies, including performance-boundary work, bio-based-content targets, dedicated products, and exclusive supply collaboration.
The BIOTEN matrix is therefore clear: BIOTEN Plus supports long-term adoption, BIOTEN Pro supports professional market entry, and BIOTEN Ultra extends performance boundaries.
On this basis, the BIOTEN Packaging water-based barrier engineering system can provide dedicated product development and collaborative supply for specialised industries.
4. From “Less, but Sufficient” to Verifiable Engineering
Low application weight is an important engineering direction. In certain typical paper-cup structures, an estimated dry coat weight of approximately 10 g/m² may place the functional layer at about 3% of the cup’s total mass, with paper accounting for about 97%.
These figures illustrate structural reduction only. Actual ratios vary with cup format, paper, and structure. They are not exemption thresholds under the PPWR, SUPD, or compostability standards, and they do not by themselves prove that a complete paper cup is recyclable, compostable, or compliant for food contact. Each of these matters requires separate assessment and evidence.
BIOTEN Packaging’s value is not to replace every decision with a single certificate. It is to advance PHA water-based barriers into professionally supplied products that can undergo value-chain review and support downstream finished-product validation.
Paper-for-plastic applications can thereby move from the idea that “a material can substitute” toward an industrial capability that is verifiable, purchasable, and consistently deliverable.
5. Supporting Industry Collaboration with Original Technology
As of August 2026, DBC and related R&D entities had disclosed 106 patents, of which 56 had been granted by the China National Intellectual Property Administration, according to the source article. More important than the count is the continuous original-technology chain being formed by granted work on bio-based waterborne barriers and PHA-based barriers, with the aim of supporting the global competitiveness of Chinese paper and packaging companies.
Representative inventions and published or granted application numbers listed in the source article include: (1) bio-based polymer emulsion, preparation method and application, CN121758933B; (2) PHA water-based barrier-coating composition and application, CN120925356; (3) PHA dispersion emulsion, preparation method and application, CN120757803B; (4) bio-based low-VOC water-based ink composition based on fermentation-derived PHA, including preparation, application and printing method, CN121319702B; (5) fully bio-based PHA aqueous dispersion, preparation method and use, CN120865687B; (6) bio-based PHA oil-resistant, moisture-permeable coating for burger wrap, coated paper and preparation method, CN120759147B; (7) PHA, PBAT and PVOH blended aqueous emulsion and its use in paper barrier coatings, CN120026524B; (8) barrier-coating composition, barrier layer and paper substrate for paper-based materials, CN119434019B; (9) mineral-based, readily recyclable and compostable water-based barrier coating and preparation method, CN120925354B; and (10) reactive compatibilised ACR–PHA core-shell latex and its application, CN120944032B.
Effective paper-for-plastic substitution is not a change that a material supplier can complete alone. Moving from an emulsion to market-ready packaging requires base-paper suppliers, coaters, converters, testing and certification organisations, and end brands to bring the substrate, process, contents, shelf life, and target market into the same project.
BIOTEN Packaging aims to organise the connection between materials and applications: linking material selection, processing adaptation, third-party evidence, and end-use validation to reduce repeated trial and error and help the right material reach the right application sooner.
A capable material is not the whole of paper-for-plastic packaging, but it can be the starting point for industry collaboration.
Only when low-use functional materials, stable manufacturing, third-party evidence, and complete product validation are connected can the industry move from “a replacement material exists” to “a solution can be delivered consistently.”
The critical layer BIOTEN Packaging seeks to provide is more than a water-, oil-, or heat-seal barrier. It connects the advantages of paper with packaging function, original technology with industrial manufacturing, circularity with composting routes, and technical development with market validation.
This is the “Paper-for-Plastic 2.0” era described in the source article. It calls on industry participants to update their understanding and establish a new foundation for global development.
China has a large and mature paper and packaging value-chain cluster. The source article identifies a global paper-for-plastic substitution opportunity of more than 30 million tonnes alongside the continuing tightening of plastic-reduction and restriction policies.
Whether the material is an acrylic barrier emulsion, PHA water-based barrier emulsion, PLA lamination, or another bio-based barrier coating, different routes will continue to coexist as the market grows. Competition will depend on professional capability and long-term commitment, while collaborative innovation offers a practical route toward high-quality scale.
Europe is reshaping global packaging rules through policy. China has an opportunity to contribute new answers through materials innovation and manufacturing capability. The convergence of policy, technology, and market demand is opening an important window for higher-quality development in paper-for-plastic packaging.
BIOTEN Packaging Barrier Systems welcomes industry partners who share this direction: working together in global markets and converting the opportunity into lasting industrial value through products that work in practice, withstand verification, and support long-term adoption.
