Poly Mailers are the main products of the external packaging of e-commerce packaging. Ordinary poly mailers need at least 100-200 years to degrade. The latest plastic ban was issued at the end of last year, and the100% degradable poly mailers rapidly attracted brands’ eyes. Let’s see from the production and characteristics of the biodegradable poly mailers, you may know why it’s so popular.
The production process of biodegradable poly mailer:
1. Raw Material Mixing: Mix the raw materials through the mixer according to a certain formula.
2. Film Blowing: Film blowing is to melt plastic particles and then blow into a film. Debug the film blowing machine and put the mixed material into the machine hopper. After stable production, attention should be paid to the thickness, size, color, corona treatment and other details of the material.
3. Printing: A printing press is used to print words and patterns. When printing we need to avoid flying ink. And need pay attention to the position when there are multiple colors.
4. Cutting and edging: The cutting machine is used to cut the blown poly mailer. When cutting, attention should be taken to whether the sealing edge is firm, whether there is any melt glue edge (too hot, extra), and whether the cutting edge is tidy.
Remarkable Characteristics of Biodegradable Poly Mailers:
Biodegradable poly mailers are made of bio-based raw materials, which can be self-degradable in compost environment to reduce environmental hazards. The main biodegradable materials are PLA+PBAT, PLA+PBAT+ corn starch, PLA+PBAT+ calcium carbonate, etc., which can be completely biodegradable into water and carbon dioxide after being buried in the ground for 180 days. The composted soil is rich in nutrients.
The raw material of biodegradable poly mailer is bio-based, it reduces the dependence on petroleum resources. And it is in line with the national biodegradation standards.
Whether the mailer is stretched lengthwise or laterally, it is very strong and has good tensile and load-bearing capacity. It is with strong toughness/explosion-proof edge toughness, tensile resistance. And the eager edge sealing process makes the mailer with strong edge tight tensile resistance.
