The big bag is a kind of big bag that uses plastic as raw material and is used to consume various daily necessities.
1. Widely used in daily life and industrial consumption, but this temporary convenience brings long-term harm. Commonly used plastic packaging bags are made of polyethylene film, which is non-toxic and can be used for food.
2. There is also a film made of polyvinyl chloride. PVC itself is not toxic, but adding additives to the film is often harmful to the human body and has certain toxicity. Therefore, this film and plastic bags made of this film are not suitable for consumption.
1) Pressure test
Put the full-load collection bag on the press for a pressure test, the pressure of the press is 4 times the weight of the bag or the static load method, that is, the self-weight of the four-layer full-load bag, and the pressurization time is more than 8 hours. In this experiment, the content does not overflow, and the bag body has no sense of damage, which means that the container has passed this test.
2) Dumping test
Fill the bag with a height of three layers, then buckle the top bag with a rope pull it down, and then observe its performance. In this test, there are no abnormalities such as damage to the base fabric and stitching of the bag, which means that the collection bag has passed the test.
The artificially accelerated aging test of the ton bag is to place the test sample of the ton bag in the test equipment, which can be simultaneously or alternately affected by factors such as light, oxygen, heat, and humidity. Under this condition, the main environmental parameters can be easily The ground remains relatively stable, so the obtained data can maintain good repeatability.
Ton bag manufacturers have stepless speed regulations for feeding and packaging, with stable equipment performance, high packaging precision, and fast speed. Programmable electronic control system, highly reliable control process. The dust-proof and dust-removal design is advanced, and the palletizer reduces dust pollution in the working environment.
