Production requirements for food plastic woven bags: a comprehensive analysis from safety to environmental protection

Production requirements for food plastic woven bags

In the modern food industry, packaging is not only a tool to protect food, but also an important link to ensure food safety and quality. Food plastic woven bags are a common packaging material with stringent production requirements. This article will analyze the production requirements of food plastic woven bags in detail, including key indicators such as thermal insulation, firmness, non-toxicity, airtightness, and how to choose food packaging bags that meet the standards.

1. Four key requirements for food plastic woven bags

1. Thermal insulation
   The thermal insulation of food packaging bags is an important factor in ensuring the freshness of food. Good thermal insulation can effectively reduce the impact of external temperature on food and prevent food from deteriorating due to temperature changes. For example, packaging bags for frozen or high-temperature foods need to have excellent thermal insulation properties to maintain the best state of food.
2. Firm application
   Food packaging bags need to withstand various external forces during transportation, so their firmness is crucial. High-quality food plastic woven bags should have strong tensile strength and abrasion resistance to avoid damage during transportation, thereby reducing food contamination and additional costs.
3. Non-toxic safety factor
   Food packaging bags are in direct contact with food, so their materials must meet food safety standards and ensure non-toxicity. Commonly used food-grade plastic materials include polypropylene (PP) and polyethylene (PE), which are not only safe and non-toxic, but also have good chemical stability.
4. Airtightness
   Airtightness is one of the core requirements for food packaging bags. Good airtightness can effectively prevent air, moisture, and microorganisms from entering the packaging and extend the shelf life of food. For example, vacuum-packed or nitrogen-filled food bags need to have extremely high airtightness to ensure the freshness and safety of food.

2. Material selection and production specifications for food plastic woven bags

1. Material selection

• Food grade resin: Commonly used food-grade resins include polypropylene (PP) and polyethylene (PE), which have the advantages of being non-toxic, odorless, and chemically resistant.
• Environmentally friendly materials: With the increasing awareness of environmental protection, more and more companies choose to use biodegradable plastics or paper materials to make food packaging bags to reduce the impact on the environment.

1. Production process

• High-temperature molding: Through high-temperature molding process, ensure the uniformity and strength of plastic woven bags.
• Surface treatment: Special treatment of the surface of woven bags, such as coating or lamination, to improve its waterproofness and wear resistance.
• Sealing test: During the production process, the packaging bags are tested for sealing to ensure that they meet the requirements of food packaging.

3. Labeling requirements for food packaging bags

According to relevant regulations, the outer packaging box of food packaging bags should contain the following information:

1. Chinese label: Indicate the company name, place of production, product name, and other information.
2. “For food use”: Mark the words “for food use” on the packaging to distinguish packaging bags for other purposes.
3. Environmental protection logo: If environmentally friendly materials are used, the corresponding environmental protection logo, such as the degradable or recyclable logo, should be marked on the packaging.

4. Environmental protection trend of food packaging bags

With the improvement of environmental awareness, the environmental protection of food packaging bags has received more and more attention. The following are some trends in environmentally friendly packaging:

1. Biodegradable plastic: Use biodegradable plastic materials, such as polylactic acid (PLA), to reduce pollution to the environment.
2. Paper packaging: Paper packaging is not only environmentally friendly but also recyclable and suitable for packaging dry food.
3. Reduce the use of coatings: Try to avoid using coatings or laminating materials to reduce the use of chemicals and their impact on the environment.

5. How to choose food plastic woven bags that meet the standards

1. Check the logo: Choose products with the words “food use” clearly marked on the packaging to ensure that they meet food safety standards.
2. Check the materials: Give priority to packaging bags made of food-grade resins or environmentally friendly materials.
3. Test performance: Test the insulation, firmness, and airtightness of the packaging bag to ensure that it meets the use requirements.
4. Choose a reputable manufacturer: Choose a qualified and reputable manufacturer to ensure product quality and after-sales service.
   
   Conclusion
   The production requirements of food plastic woven bags are not only related to food safety and quality but also directly affect the health of consumers and the sustainable development of the environment. By strictly following key requirements such as insulation, firmness, non-toxicity, and airtightness, and selecting environmentally friendly materials and standardized production processes, companies can produce high-quality food packaging bags that meet standards and provide consumers with safe and healthy food packaging solutions.
