OPP bag
-
Biaxially oriented polypropylene bag
-
Substrate:polypropylene film is made by biaxial stretching process.
-
Product features:
-
High transparency:high transparency, close to cellophane, can clearly display the contents, enhance product display effect.
-
High Gloss:surface bright, high-grade appearance.
-
High hardness/stiffness:material is more rigid, not easy to deformation, can maintain a better packaging form, protect the contents from being crushed.
-
Good printability:surface is smooth, suitable for exquisite printing, and the pattern is colorful and clear.
-
Moisture resistance is better:has a certain moisture resistance.
-
Costs are relatively low:raw materials and production costs are relatively advantageous.
-
Disadvantages:
-
Poor toughness:is relatively brittle, tear resistance and impact resistance are not as good as PE bags, and it is easy to break when sharp objects or excessive force.
-
Heat sealing performance in general:heat seal strength is not as good as PE bag.
-
Poor low temperature resistance:will become brittle at low temperatures.
-
Air permeability:has a certain degree of breathability, not suitable for the need for high barrier properties (such as oxygen, fragrance) products.

-
Practical application scenarios:
-
Clothing and Textiles:transparent outer packaging bags (tag bags) for shirts, T-shirts, socks, underwear, towels, etc., show good results.
-
Stationery, greeting cards:protective packaging for notebooks, pens, greeting cards, photo albums, etc.
-
Electronic products accessories:instructions, data lines, headphones, small parts and other independent packaging bags.
-
Print:protective cover for brochures, catalogues, magazines, etc.
-
Light industrial products:toys, hardware, handicrafts, etc.
-
Food (partial):used for packaging dry foods that do not require high barrier properties, such as biscuits, candies (the inner layer often has other materials), dry goods, and some snacks.
