What are the requirements of the paper bag machine for materials
1. According to the different uses of paper bags, the materials of packaging bags should have resistance to moisture, water vapor, gas, light and heat, and also need to have a certain impact strength, vibration strength and packaging humidity, etc. And it is necessary to have a certain ability to protect the packaged items. In order to meet people's requirements for packaging bags.
2. When selecting materials, the toxicity of packaging materials should be small, especially food packaging bags, which absolutely cannot release poisons, otherwise it will affect the promotion and application of paper bags and have certain anti-microbial performance. However, the materials used to make packaging bags by paper bag machine are made of paper, which can meet this condition. The packaging materials can be produced on a large scale, which can meet people's daily needs, reduce the price of materials, facilitate mechanization, automation, can adapt to printing, and can also print logo marks on packaging bags.
4. The resources are relatively rich, and the materials are very convenient and the cost is relatively low. The packaging bags after use can be recycled without causing environmental pollution. This is one of the fundamental reasons for eliminating plastic bags.
In general, the production material of paper bags needs to meet the requirements of people's daily life, and has high safety and environmental protection.
