Detailed Introduction:

There is a thin film on the outside of laundry gel beads, which I believe everyone knows.

 The film is wrapped with laundry gel beads and can be directly put into the machine for washing.

 What are the characteristics of the film?

 Let's take a look together below!

The biggest feature of laundry gel beads is the thin film they are wrapped in. In a dry environment, they are highly resilient and require some effort to be squeezed out. However, their fatal weakness and advantage are that they are easily soluble in water. With just a small drop, the gel beads will rupture, and the clean and purified inside will flow out naturally.

Plastic film is made of a water-soluble material called polyvinyl alcohol (PVA, PVOH or PVAL for short).

 Water soluble materials, as the name suggests, are soluble in water.

 Polyvinyl alcohol is a highly water-soluble polymer material characterized by good density, strong adhesion, flexible and smooth thin films, oil resistance, solvent resistance, wear resistance, good gas permeability, and water resistance after special treatment. It can control the temperature and speed of water solubility and has a wide range of applications, including textile, food, medicine, construction, wood processing, papermaking, printing, agriculture, steel, polymer chemical and other industries.

The most important point is that polyvinyl alcohol is an extremely safe polymer organic compound, non-toxic to the human body, and has no side effects.

 Consumers do not need to worry about harmful substances remaining in laundry gel beads during the washing process, as polyvinyl alcohol film is also used in medicinal films, artificial kidney films, and other fields. Its safety can be seen from its use in wound skin repair and eye drops products.

In addition, polyvinyl alcohol film has good affinity with the natural environment, does not accumulate, is pollution-free, and is a green and pollution-free environmentally friendly material.

 Within 180 days, polyvinyl alcohol water-soluble film can be decomposed by bacterial strains isolated from the soil, ultimately degrading into CO2 and H2O, and has a land improvement effect.
