BOPP/OPP, commonly known as biaxially oriented polymer
Acrylic film
Colorless, odorless, tasteless, non-toxic, and possessing high tensile strength, impact strength, rigidity, toughness, and good transparency. But it is prone to accumulating static electricity and has poor heat sealing performance.
CPP, commonly known as cast polypropylene film/stretch polypropylene film
Excellent moisture and odor barrier properties, as a food and commodity packaging and outer packaging, it has excellent demonstration properties and can make products clearly visible under the packaging. CPP has excellent heat resistance (PP softening point is about 140 ° C, which can be used in fields such as hot filling, steaming bags, sterile packaging, etc.), safe contact with food, excellent demonstration performance, and will not affect the flavor of the packaged food. Different grades of resin can be selected to obtain the desired characteristics.
CPP aluminum, commonly known as CPP aluminum coated film
Metallic film for barrier packaging and decoration. After vacuum aluminum plating, it has good light shielding properties and can be combined with BOPPBOPA and other substrates for high-end packaging of tea, fried and crispy foods, biscuits, etc.
PE, commonly known as polyethylene
Polyethylene is odorless, non-toxic, and feels like wax. It has excellent low-temperature resistance (with a minimum operating temperature of -100-70 ° C), good chemical stability, and can withstand most acid and alkali corrosion (not resistant to acids with oxidizing properties). Insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation.
PET, commonly known as polyester resin, is a condensed polymer of terephthalic acid and ethylene glycol
1. It has good mechanical properties, with an impact strength 3-5 times that of other films and good flexural resistance
2. Resistant to oil, fat, oleic acid, dilute alkali, and most solvents.
3. The heat resistance of pure PET is not high, with a heat deformation temperature of only about 85 ° C, but it is significantly improved after reinforcement treatment. The mechanical properties of PET reinforced with fiberglass are similar to engineering plastics such as PC and PA, and the thermal deformation temperature can reach 225 ° C; PET has good heat aging resistance, with a brittleness temperature of -70 ° C, and still has a certain toughness at -30 ° C; PET is not easy to burn, with a yellow flame and droplets of burning oil.
4. Low gas and water vapor permeability, with excellent gas barrier, water, oil and odor resistance properties.
5. High transparency, can block ultraviolet rays, and has good luster.
6. Non toxic, odorless, with good hygiene and safety, can be directly used for food packaging.
APET, commonly known as amorphous polyethylene terephthalate
APET products are pollution-free, crystal free, have high transparency, good smoothness, and strong impact resistance. They can be widely used for exquisite packaging such as vacuum forming, folding boxes, cylinders, and various printing window films. They can also produce various color films according to customer requirements.
PA, commonly known as polyamide (PA, commonly known as nylon)
