Specific application scenarios of film blowing machines in the food packaging industry
Food cling film
The film blowing machine is used to manufacture food cling film with barrier properties, which is particularly suitable for packaging fresh fruits, vegetables, meat and other foods. With the continuous improvement of people's living standards, more and more attention has been paid to food safety issues. Many new environmentally friendly cling films have appeared on the market, such as biodegradable, non-toxic and harmless, and high barrier types. This type of cling film can not only effectively isolate external pollution such as oxygen and water vapor, but also extend the shelf life of food, ensuring that food remains fresh and safe during circulation.
Frozen food packaging
For frozen food, its packaging material needs to have sufficient low temperature tolerance to prevent brittle cracking in low temperature environments. Plastic film for frozen food packaging is a special material with good light transmittance and barrier properties. The frozen food film produced by the film blowing machine not only has excellent cold resistance and moisture resistance, but also can maintain the quality of food in a frozen storage environment and effectively prevent water evaporation and frostbite.
Heat-sealed bags and retort bags
The film blowing machine also has the ability to produce retort bags and heat-sealed bags suitable for heating under high temperature conditions. These packaging materials are particularly suitable for ready-to-eat foods and high-temperature sterilization occasions. In the field of food packaging, vacuum heat sealing technology is currently the most widely used packaging material. This material has excellent high temperature resistance and chemical stability, can withstand microwave heating and cooking, will not release toxic substances, and fully meets the hygiene standards of food packaging.
Snacks and leisure food packaging
The multi-layer composite film material produced by the film blowing machine is very suitable for the packaging of snacks and nuts. At present, there are many multi-layer composite film products for food packaging on the market. This packaging film has excellent barrier, tear resistance and sealing properties, which can effectively extend the shelf life of food on the shelf, resist the invasion of external moisture and oxygen, thereby maintaining the taste and freshness of food.
How can the film produced by the film blowing machine meet the high requirements of food packaging for safety and hygiene?
Use raw materials that meet food grade standards
In the process of using the film blowing machine for food packaging, materials that meet food grade standards must be selected to prevent the release of harmful substances. This article develops corresponding control methods and control measures by testing and analyzing the packaging materials and the use environment, and applies them in the actual production process. Doing so ensures safe contact between food packaging and food, thereby reducing the adverse effects on the taste and quality of food.
Pollution-free production environment
The manufacturing environment of the film blowing machine must be maintained in a clean state to reduce the risk of foreign matter or contaminants entering the film material. Therefore, the production process and products must be kept free of contamination. In the production workshop, we must implement dust-free and sterile operations, and regularly clean and maintain all production equipment.
Corrosion resistance and chemical stability of the film
The chemical stability of the film blown is very critical. The packaging material must have good acid and alkali resistance to prevent chemical changes when in contact with food, and ensure that it will not adversely affect the taste and composition of food during transportation and storage.
Testing and certification of product compliance
Food packaging films manufactured by HDPE FILM BLOWING EXTRUDER must obtain food safety certifications such as FDA and EU to ensure their global hygiene compliance and protect the safety of consumers during use.
