Ürün Açıklaması
CPP aluminized film for frozen foods, -20℃ low temperature resistant and crack-resistant CPP metal film
Dear customer, seeing this message is a very important moment for us. These are our flagship products. In addition, VMPET and VMPE are also among our strengths. We also offer excellent quality and competitive prices for transparent films such as CPP/BOPP/PE.
Trust me, leave your information, and I won't let you down.
| Comparison Dimension | CPP Aluminum-Plated Film | VMPET (Aluminum-Plated PET Film) |
| Heat Sealing Performance | Excellent (direct heat-sealable, heat-sealing temperature: 120~150°C) | Poor (PET substrate cannot be directly heat-sealed; requires lamination with PE/PP heat-sealing layer) |
| Barrier Performance (Oxygen/Water) | Good (OTR ≤1, WVTR ≤1) | Excellent (OTR ≤0.5, WVTR ≤0.5) |
| Specific Gravity / Weight | 0.91g/cm³ (lightweight) | 1.4g/cm³ (heavier) |
| Low-Temperature Adaptability | Excellent (no embrittlement at -20°C) | Poor (prone to embrittlement at low temperatures; easy to break at ≤-10°C) |
| High-Temperature Resistance | Good (can withstand 120°C high temperature; supports microwave heating) | Excellent (can withstand temperatures above 150°C) |
| Cost | Relatively low (PP raw material is cheaper than PET; production process is simple) | Relatively high (PET raw material is expensive; aluminum-plating process has higher requirements) |
| Flexibility and Tear Resistance | Good (high flexibility, tear-resistant) | Excellent (high rigidity, tensile-resistant, but average flexibility) |
| Recyclability | Good (polypropylene material is easy to recycle) | Average (PET material is more difficult to recycle than PP) |
I. Core Characteristics of CPP Metallized Film
CPP (Cast Polypropylene Metallized Film) is made by vacuum metallizing polypropylene film produced through a casting process. It combines the advantages of both a CPP substrate and a metallic aluminum layer. Specific characteristics are as follows:
Physical and Mechanical Properties: Good stiffness and rigidity, not easily deformed, and tear resistance superior to PE film, suitable for high-speed printing and lamination; Excellent heat-sealing performance (especially the CPP heat-sealing layer), allowing direct heat sealing without additional adhesive or lamination; Wide temperature range (-20℃~120℃), capable of withstanding high-temperature sterilization (such as pasteurization of some food packaging), and not easily brittle at low temperatures.
Barrier Properties: The aluminized layer (typically 300~500Å thick) effectively blocks oxygen (OTR≤1cm³/(m²・24h・0.1MPa)), water vapor (WVTR≤1g/(m²・24h)), and light (especially ultraviolet light), extending the shelf life of packaged goods; Barrier properties are slightly lower than VMPET, but far superior to un-aluminized CPP or PE film.
Other characteristics: Medium transparency (silver-gray after aluminizing, transparent in un-aluminized areas), good gloss, metallic texture, enhancing packaging aesthetics; Strong chemical stability, resistant to acids, alkalis, and oils, suitable for packaging oily or acidic foods; Lightweight (0.91g/cm³), lighter than VMPET (1.4g/cm³), reducing transportation and packaging costs; Good recyclability (polypropylene material), more environmentally friendly than some composite films.
II. Specific Applications of CPP Aluminized Film
Based on its core advantages of "barrier properties + heat-sealing properties + lightweight," it is widely used in the following fields:
1. Food Packaging (Core Application Scenarios)
Snack Foods: Outer packaging for potato chips, biscuits, candy, chocolate, and nuts (often laminated with PE film to form a "CPP aluminized + PE" structure, combining barrier and heat-sealing properties);
Dried Goods: Packaging for tea, coffee, milk powder, oatmeal, and dehydrated vegetables (barrier against oxygen and moisture, extending shelf life);
Oil and Fat Foods: Packaging for edible oils, sauces, meat products, and seafood (oil-resistant, strong barrier properties, preventing oxidation and spoilage);
Microwaveable Foods: Packaging for some microwaveable frozen and ready-to-eat foods (high temperature resistant, can be directly heated).
2. Daily Necessities Packaging
Cosmetics: Inner film of outer packaging boxes for face masks, skincare products, and shampoos (barrier against moisture and oxygen, protecting active ingredients);
Daily Necessities: Packaging for tissues, wet wipes, sanitary napkins, and diapers (moisture-proof, dust-proof, enhances texture);
Tobacco Packaging: Inner packaging film for cigarettes (strong barrier properties, maintains tobacco dryness and flavor).
3. Industrial and Other Packaging
Electronic Components: Packaging for resistors, capacitors, chips, etc. (moisture-proof, anti-static, dust-proof);
Pharmaceutical Packaging: Outer packaging for some medicines (strong barrier properties, protects drug stability, must meet pharmaceutical-grade standards);
Composite Film Substrates: Composite with PET, PE, NY (nylon), etc., for heavy-duty packaging (e.g., fertilizer, feed bags) or high-barrier applications (e.g., vacuum packaging).
