In the modern food packaging industry, food-grade blister packaging has become an important means of protecting food quality and extending the shelf life of food due to its excellent preservation performance, transportation convenience and cost-effectiveness. However, ensuring the safety and compliance of food-grade blister packaging is a key challenge that manufacturers must face.
1. Raw material selection
The raw materials of food-grade blister packaging are the basis for ensuring packaging safety. Commonly used raw materials include PVC, PET, PS, PP, PETG, etc. Each material has its own unique physical and chemical properties. When selecting, it is necessary to comprehensively consider factors such as transparency, toughness, temperature resistance, environmental protection and cost. For example, PET has good toughness, high transparency, recyclability and does not produce harmful gases when burned, making it an environmentally friendly and high-end blister packaging material. PP is also one of the ideal food packaging materials because of its non-toxic, odorless, good chemical stability and high temperature resistance.
2. Production process requirements
The production process of food-grade blister packaging must be fine to ensure the quality and safety of the product. The mold needs to be thoroughly cleaned and dried to avoid contamination by impurities. At the same time, the mold surface should be smooth and flawless to ensure the appearance quality of the molded product. During the blister molding process, parameters such as temperature, pressure and time must be strictly controlled to ensure that the product wall thickness is uniform and there are no defects such as bubbles and cracks. In addition, environmental hygiene should be strictly controlled during the production process to avoid cross contamination. Operators need to wear neat work clothes, masks and gloves to reduce contamination of the product.
3. Hygiene and safety requirements
Food-grade blister packaging must meet strict hygiene and safety requirements to ensure that food is not contaminated during the packaging process. The selected raw materials should comply with relevant national health standards, such as GB13114-1994 "Sanitary Standards for Polyethylene Terephthalate Resins for Food Containers and Packaging Materials", GB9689-2003 "Sanitary Standards for Polyethylene, Polystyrene, and Polypropylene Molded Products for Food Packaging". The finished product must undergo strict inspection, including inspections of appearance quality, dimensional accuracy, and hygiene indicators. Only products that meet the standards can be shipped and sold.
4. Environmental protection requirements
With the improvement of environmental awareness, the environmental protection requirements of food-grade blister packaging are becoming increasingly stringent. The selected materials should have good recyclability to reduce pollution to the environment. Measures should be taken during the production process to reduce the generation of waste, such as optimizing mold design and improving material utilization. In addition, the use of green packaging materials and technologies, such as biodegradable materials, is encouraged to reduce the burden on the environment.
