How to produce biodegradable shopping bags?

The production of biodegradable carrier shopping bags usually requires the use of film blowing machines and bag making machines.

1. Film blowing machine: Film blowing machines are used to produce plastic films, including biodegradable materials. For the production of tote bags, you may need to purchase a medium or high speed blown film machine to meet higher capacity requirements. These machines are capable of heating and extruding plastic pellets into film. The Biodegradable Online Gravure Printing Plastic Film Blowing Machine (shaftless) manufactured by Chaoshin Machinery can meet your needs.

2. Bag Making Machine: Bag making machine is used to cut, fold and seal the blown plastic film into the shape of a shopping bag. For the production of biodegradable tote bags, you need to make sure that the bag making machine you buy can adapt to the characteristics of biodegradable materials and has efficient production capacity. The High-Speed Plastic Bag Making Machine (Two Lines) from Chaoshin Machinery can meet your production needs.

The process of producing biodegradable shopping bags using a film blowing machine and bag making machine:

1. Preparation of biodegradable plastic pellets: obtain biodegradable plastic pellets that meet the requirements.
2. Blown film production: Put the biodegradable plastic pellets into the hopper of the film blowing machine.

Start the film blowing machine to allow the plastic pellets to be heated and extruded into film. Adjust the parameters of the film blowing machine to ensure that the required film thickness and width are produced. Controls the cooling system of the film blowing machine to stabilize the temperature and structure of the film.

Printing and Additives:

Prints on the film to add patterns, text or logos. Changing the color of plastic bags or adding biodegradable additives can be adjusted accordingly during the blown film process.

Bag making: The blown film is fed into the bag making machine. The bag making machine will cut the film to the required size according to a preset program and fold, position and seal it to form the structure of the shopping bag. Ensure that the sealing system of the bag making machine can effectively close the bottom and sides of the bag to ensure its sealing performance.

During the production process, adjustments and optimizations need to be made according to the requirements of the product and the performance of the equipment to ensure the production of biodegradable shopping bags with stable quality and meeting the requirements. Meanwhile, the film blowing machine and bag making machine should be regularly maintained and serviced to ensure their stable operation and prolong their service life.
