Oxygen barrier properties: The vacuum aluminum layer provides an excellent oxygen barrier effect, which can maintain the intrinsic quality of the product for a long time, such as the aroma, color and nutrients of the food, and effectively prevent oxidation and deterioration.
Moisture-proof performance: Similarly, the presence of the aluminum layer greatly improves the film's barrier ability to water vapor, which is suitable for packaging that requires moisture-proof, such as tea, bread, dried fruits and other products.
2. Good mechanical properties
Strength and toughness: The composite film combines the excellent mechanical properties of the polypropylene substrate, so that the packaging has good tensile and tear resistance, ensuring that it is not easily damaged during transportation and storage.
Puncture resistance: For packaging fragile goods or items with sharp edges, VPP film shows excellent puncture resistance and maintains the integrity of the packaging.
3. Transparency and gloss
Beautiful display: VPP film usually has good transparency and gloss, so that the appearance of the product can be perfectly displayed in the packaging, improving the visual effect of the product and attracting the attention of consumers.
Smooth surface: The vacuum aluminum coating makes the film surface extremely smooth, which is not only beautiful and generous, but also convenient for printing exquisite patterns and texts, further enhancing the attractiveness of the packaging.
4. Diversified printing performance
Excellent printing suitability: The surface of the composite film can adhere to ink well and is suitable for various printing technologies such as flexographic printing, gravure printing and silk screen printing, and can print colorful and complex patterns.
Heat sealability: VPP film has excellent heat sealing performance, is easy to make bags, suitable for automatic packaging lines, and improves production efficiency and product quality.
5. Environmental performance
Reduced material use: Compared with metal cans or glass packaging, VPP film is lighter in use, reduces material use, and reduces transportation costs and carbon emissions.
Recyclability: If there is no special coating or additives inside, VPP film can be recycled and reused, which meets the current environmental protection trends and regulatory requirements.
6. Versatility and Application
Wide Application: VPP film has been widely used in the packaging of a variety of commodities such as food, medicine, cosmetics, and electronic products due to its multiple advantages. It can provide excellent protection and display effects for both large and small packages.
Strong adaptability: It can be laminated in a variety of ways, such as with other high barrier materials (such as EVOH, nylon) or functional materials (such as antistatic agents), further expanding its functionality and application range.
7. Safety Performance
Keep product safety: VPP film performs well in light, dust, and odor protection, and can provide a relatively sealed and safe environment for products such as food and medicine to maintain the freshness and quality of the products.
Meet food contact standards: If used for food packaging, VPP film must meet relevant food safety standards to ensure that there is no migration of harmful substances and protect consumer health.
Vacuum Aluminized Cast Polypropylene Composite Film BOPP demonstrates multiple advantages in perfect packaging, including high barrier properties, good mechanical properties, transparency and gloss, diverse printing performance, environmental performance, versatility and application range, and safety performance. These features enable it to provide excellent protection and display effects in the packaging of a variety of commodities, meeting the multiple requirements of contemporary packaging for high performance, environmental protection and aesthetics.
