Keep Healthy with Yumyth Co-extrusion Bags





In addition to the key role of vacuum sealer, the function of vacuum sealing bag should not be ignored when preserving food. However, many unprofessional customers are often deceived by "gimmicks" in the market. Some businesses use lower costs to make vacuum sealing bags with proof quality, but tell consumers that the quality is very good, and consumers are often deceived by their "professionalism".

Now this news is to help people identify what is a good vacuum bag and what is the best bag for sealing food. Vacuum sealed bags can be divided into two types, multi-layers co-extrusion bags and composite bags.

What is The Co-extrusion Bag?
A bag made of several materials such as PA+PE, no solvent, no heavy metal residue, no delamination (-20℃-100℃), excellent tensile property, puncture resistance and other characteristics. According to the different recipes, the toughness of the bag will have different effects, but it is more recommended that the bag made of PA+PE has medium cost and significant effect.

However, composite bag is on the contrary. Composite bag is a cheap bag that used chemical solvent to bond nylon and PE, which is easy to cause chemical solvent residue and easy to be stratified (-20℃-50℃) under high temperature for a long time. The bag is not tough enough for store hard food, and easy to puncture. Besides, the formula is unique and cannot be changed.
The comparison photo of co-extrusion bag and composite bag is as follows:


Discovery:
