Polyethylene (PE) is made by polymerization of ethylene monomer, nCH₂ = CH₂ →（—CH₂—CH₂—)_n, while n is implying the degree of polymerization. With the relative molecular weight is above 50000, polyethylene is the most consumed variety among all the plastic packaging films.

The packaging of consumed foods can be divided into convenient food, puffed food, pastries & biscuit, dairy product & baked goods, candy & preserved fruit, meat product, pre-made food, roasted nuts, frozen food,health care, grain & oil, sauce, wine & beverage, tea & instant drink etc.

This issue is common in PET (printing film)/aluminum foil lamination. Aluminum foil adhesives generally have higher viscosity than other flexible packaging adhesives. When the thickness distribution of multicolor ink is uneven, the adhesive may not fully fill the ink pits during curing, resulting in visible white spots.
