Food aluminum spout pouch material is often used in people's daily life, but it must be used with care. Some food aluminum spout pouch material is poisonous and cannot be used directly to serve food. Here are some tips I learned while making food aluminum spout pouch material.

observation with eyes

Non-toxic plastic bags are white, shiny or slightly shiny and have a uniform texture. Toxic plastic bags are colored or white, but they are poorly lit, dirty, stretch unevenly, and have small particles.

listen with ears

When shaking the plastic bag by hand, the crisp sound proves that it is a non-toxic plastic bag. The sound is low and muffled is the poisonous plastic bag.

touch with hand

Touch the appearance of the aluminum spout pouch material of the food with your hands. Lubrication is non-toxic. Sticky, astringent, and waxy ones are toxic.
