Multi-layer kraft paper bag machine The paper bag machine is equipped with advanced electrical systems and mechanical devices from the base material feeding, tube forming, sticking, cutting, conveying and stacking. It adopts Taiwan servo system and human-machine interface. The substrate is continuously processed in one process from feeding to the finished product with high degree of automation. The bag making technology is advanced, the equipment structure is reasonable, and the tube bag is beautiful and reliable. It is the ideal equipment for various types of packaging bags production at home and abroad.
        1. According to the purpose of the paper bag, the material of the packaging bag should have resistance to moisture, water vapor, gas, light and heat, etc., and also need to have a certain impact strength, vibration strength and packaging humidity, etc. Packaged items have certain protective capabilities. This can meet people's requirements for packaging bags.
        2. When selecting materials, the toxicity of packaging materials should be small, especially food packaging bags, which must not be able to release poisons, otherwise it will affect the promotion and application of paper bags and have certain anti-microbial properties, but Paper bag machines are used to make packaging materials made of paper, which can meet this condition.
        3. The packaging materials can be produced on a large scale, which can meet people's daily needs, reduce the price of materials, facilitate mechanization and automation, be able to adapt to printing, and also print logos and trademarks on packaging bags.
        4. The resources are abundant, and the materials are very convenient, and the cost is relatively low. After use, the packaging bags can be recycled and reused without causing environmental pollution. This is one of the fundamental reasons for eliminating plastic bags.

        In general, the production materials of paper bags need to meet people's daily use requirements, and have high safety and environmental protection.
