The main materials used for packaging daily necessities include PVC, PET, PP, and PS. PVC is widely used due to its high transparency and low cost, while PET stands out for its environmental friendliness.
In terms of manufacturing, stamping technology softens plastic sheets by heating them, then uses molds to shape them into the desired form. A slitting machine then cuts the shaped sheets into individual packaging boxes. Wireless plastic component binding avoids the use of traditional glue or metal staples, reducing the risk of chemical residues. The pH value is controlled between 4.0 and 6.0 to ensure material stability and prevent reactions with the packaging contents.
