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.  

A representative delegation from a well-known curry food enterprise in Singapore visited Guangzhou Rosin Packaging Co., Ltd. in Guangzhou specifically to conduct on-site factory inspections. This time, the client focused on conducting a special audit and technical exchange on the curry food special vacuum sealed tray, gaining a deep understanding of the company's production strength, quality control system, and customized packaging capacity, laying a solid foundation for the subsequent deep strategic cooperation between the two parties. As a professional manufacturer deeply involved in the vacuum formed packaging industry for many years, Guangzhou Rosin Packaging has been dedicated to the research and development and production of various food grade vacuum formed packaging products since its establishment in 2010. Its main products include food vacuum formed heat sealed trays, vacuum formed trays, and customized heat sealed packaging. The company has standardized dust-free production workshops, advanced fully automatic negative pressure suction molding machines, and integrated positive and negative pressure production equipment. At the same time, it has complete testing instruments and strictly follows food packaging safety production standards. It holds a production license for food blister packaging and has passed the dual certification of ISO9001 quality management system and ISO14001 environmental management system. From raw material selection, production and processing to finished product testing, the entire process strictly controls quality, fully meeting the safety packaging requirements of food enterprises at home and abroad. During the inspection period, accompanied by the company's business leader and technical team, the Singaporean client visited the production workshop, quality inspection laboratory, and sample display area. The customer conducted in-depth technical discussions with technical personnel from both parties regarding special usage scenarios such as storage, cold chain transportation, high-temperature heat sealing, and cross-border transportation of Singaporean curry food. Optimization plans were finalized on details such as tray thickness, sealing process, food grade environmentally friendly materials, and customized appearance. During the business discussion session, both parties engaged in detailed discussions on cooperation matters such as product customization, production delivery time, cross-border supply, pricing system, and after-sales support. Taking into account the consumption characteristics of the Singapore food market, they finalized cooperation plans for subsequent sample making and mass production. The customer stated that after this on-site inspection, they fully recognize the comprehensive strength of Guangzhou Rosin Packaging Co., Ltd. Their professional food vacuum packaging solutions can accurately match the packaging upgrade needs of curry food. They look forward to building a long-term and stable str...
