Custom Stand Up Bags & Pouches-Ewaybag

Stand-up pouches are a kind of plastic packaging bags that can stand up, usually with two or three, or four layers of material laminated into such as PET/PE, PET/CPP, OPP/PE, OPP/CPP, PA/PE, PET/AL/PE, OPP/AL/PE, etc.

Stand-up pouches are also widely used in clothing and apparel, food, hardware and electronics, daily necessities, medical supplies, etc. Our stand-up pouches are FDA approved and can be in direct contact with food.

1, polyethylene (PE) polyethylene is a thermoplastic polymer of ethylene; polyethylene is a milky white waxy solid, lighter than water, softer, water resistant, low temperature, tasteless, and non-toxic, according to its density. It can be divided into high-density, medium-density, low-density polyethylene, and linear low-density polyethylene (LLDPE).

2， polypropylene (PP) polypropylene is a by-product of petroleum refining propylene and is known as a small plastic;
It is non-toxic, odorless, has high transparency, mechanical properties, surface strength, friction resistance, chemical resistance, and moisture resistance are excellent; impact resistance value is considerable above room temperature.
PP is widely used in the food industry, mainly used to manufacture film and composite film; PP has good transparency and surface gloss and can resist 120 degrees temperature; PP can also be made into packaging boxes, blowing molding into plastic bottles.

3, polystyrene (PS) polystyrene is a colorless, transparent, non-ductile thermoplastic; it is non-toxic, tasteless, odorless, good coloring, moisture permeability greater than polyethylene, low moisture absorption, dimensional stability, good luster; good processing performance, low cost;
Its mechanical properties increase with the increase in molecular weight; PS has low-temperature resistance and can withstand -40 ℃ low temperature; it has good indoor aging resistance; it has good resistance to alcohol organic solvents, mineral oil, acid, and alkaline performance is also very good.
Polystyrene, due to its superior performance, low price, and wide application, can be made into film, and containers, widely used in the food industry; a shrinkage rate of up to 60-70, is a good material for the production of shrink packaging.
