In the global wave of plastic pollution control, bamboo, a rapidly growing and biodegradable natural material, is entering the field of vacuum formed products with its unique physical properties and environmental advantages, becoming a part of replacing traditional plastics. They are mostly made by blending bamboo fiber/bamboo powder with fully biodegradable materials such as PLA and RPET, and then forming them into sheets through vacuum forming/molding processes. They are widely used in scenarios such as food delivery, food packaging, and logistics lining. There is currently no authoritative national unified statistical data on the market share of bamboo vacuum formed products in the food and beverage delivery field, and its approximate position can only be understood from the current industry situation and local data. Overall market share: Still a niche market, but growing rapidly. Market size: In 2024, the sales volume of disposable lunch boxes in China is about 84.9 billion, with plastic lunch boxes still dominating. Bamboo products positioning: Bamboo fiber lunch boxes, tableware, etc. belong to "environmentally friendly alternatives". According to monitoring by the Ministry of Commerce, the usage of such substitutes increased by 26.31% month on month in the first half of 2025, indicating that they are in a period of rapid penetration, but the base is still small, in the single digits, and far from becoming mainstream in the market. After purchasing fresh bamboo leaves and bamboo slices for the production project of "replacing plastic with bamboo", they are subjected to coarse crushing, ultrafine crushing, graded screening, and drying to obtain ultrafine powder with a mesh size of 500-5000. Some ultrafine powders are sold as products, some are mixed with PLA and PBAT for granulation to obtain biodegradable particles A, some are mixed with PLA for granulation to obtain biodegradable particles B, and some are mixed with PLA and PBAT for injection molding into packaging boxes. Part of the biodegradable particles are sold as products, and some of the biodegradable particles A are blown to obtain biodegradable plastic film. After blowing and bag making, biodegradable express bags are obtained, and biodegradable lunch boxes are obtained through vacuum forming; Partially biodegradable particles B are injected into biodegradable cups, bowls, knives, forks, and spoons.

Guangzhou Rosin Packaging Co., Ltd. has developed an injection grade low precipitation, low-temperature resistant recycled PP material using food grade recycled polypropylene as raw material, through three-stage heat treatment and low-temperature blending modification technology. This material has passed FDA, ROHS, REACH contact safety testing and has an impact strength of over 3 kJ/m ² at -15 ℃, far exceeding that of homopolymer PP-H raw materials. It completely solves the problem of unstable adhesion during secondary processing and provides a high-performance solution for the low-carbon transformation of the daily chemical packaging industry. Industry pain points: Dual constraints of low-temperature brittleness and precipitation issues In the field of plastic packaging and products, homopolymer polypropylene occupies an important position due to its excellent hardness and transparency, and is widely used in packaging scenarios such as food, daily chemical, pharmaceutical, etc. However, its low-temperature brittleness issues constrain its application boundaries. When the ambient temperature drops from 23 ℃ to 0 ℃, the notch impact strength of PP-H cantilever beam sharply decreases from about 3 kJ/m ² to 1.5 kJ/m ², and further drops to 0.7 kJ/m ² at -15 ℃. This performance cliff makes PP-H products prone to cracking in winter, which not only affects the user experience but also increases the external packaging and after-sales costs of the enterprise. Polypropylene materials also commonly face the problem of precipitation. Residual small molecule substances such as ethylene monomers, lubricants, and release agents in raw materials will migrate to the surface of the product over time, seriously affecting the adhesion of secondary processing such as spraying, electroplating, printing, and hot stamping. Many companies have encountered the embarrassing situation of good adhesion during the initial spraying stage, but failure in the hundred grid test after one month of storage. What is even more troubling is that the differences in precipitation tables between different petrochemical grades or even different batches of the same grade seriously interfere with production stability and quality control consistency.
