This effectively extends the freshness period of food and prevents drug oxidation.
- Upgraded Weather Resistance: It can withstand a wide temperature range from -30°C to 120°C. The anti-embrittlement performance retention rate is ≥95% in the -30°C freezing test, and no delamination occurs after 30 minutes of 蒸煮 at 120°C, adapting to the packaging needs of frozen foods and high-temperature sterilization.
(B) Optical and Mechanical Properties: Both Aesthetics and Strength
- Metallic Aesthetic: With a glossiness of up to 150GU, it supports customized coating effects such as matte and laser, and the reflectivity ≥85%, enhancing the high-end visual experience of luxury packaging and gift boxes.
- Tough and Durable Design: The tensile strength (MD/TD) reaches 58.9/51.8MPa, the elongation at break (MD/TD) is 370/460%, and the puncture resistance ≥35N. Even when loading granular foods or heavy industrial parts, it can withstand transportation impacts.
(C) Food-Grade Safety and Environmental Commitment
- Compliance Certification: It has passed food contact material certifications such as FDA and GB 4806, with an aluminum layer migration amount ≤0.05ppm and no plasticizers (phthalates ≤0.1%), ensuring the safety of direct food contact.
- Sustainable Innovation: It has launched recyclable metallized CPP films with an aluminum layer and PP substrate separation recovery rate of 85%, and participated in the EU “New Plastics Economy” initiative. By 2025, it will achieve full product line carbon footprint transparency.
II. Application Scenarios: Packaging Innovation Across Industries
(A) Food and Beverage: From Freshness Preservation to Brand Upgrading
- Snacks and Baked Goods: 20μm metallized CPP films are used for potato chips and coffee bean packaging, with WVTR ≤2.0g/(m²·day), extending the shelf life to 18 months. High-end baking brands customize matte metallized films with hot stamping processes, increasing product premiums by 30%.
- Prepared Foods and Frozen Foods: 30μm heat-resistant metallized CPP composite films are used for self-heating hotpot packaging, which can withstand 121°C high temperature for 2 hours. At the same time, laser perforation technology is supported to achieve air pressure balance in the packaging and reduce the risk of bag swelling.
(B) Pharmaceuticals and Cosmetics: Precise Protection and High-End Texture
- Pharmaceutical Packaging: Metallized CPP films are used as the inner layer of pharmaceutical aluminum-plastic blisters, with a light-shielding rate ≥99%, suitable for light-sensitive drugs such as nitroglycerin and vaccines. It has passed the ISO 15378 certification, with a microbial contamination rate ≤10CFU/100cm².
- Cosmetic Packaging: High-gloss metallized CPP films are used for skin care product aluminum bags, which are resistant to cosmetic oil corrosion (performance retention rate ≥95% in pH 3-11 environments). At the same time, embossed printing is supported, with a delicate touch, enhancing the unpacking experience of high-end skin care products.
(C) Industrial and Electronic: Preferred Solutions for Precise Protection
- Electronic Component Packaging: Anti-static metallized CPP films (surface resistance ≤10⁹Ω) are used for semiconductor moisture-proof bags, with electromagnetic shielding effectiveness ≥60dB, protecting 5G chips and sensors from static electricity and electromagnetic interference. It has entered the supply chains of Intel and TSMC.
- Lithium Battery Packaging: 25μm metallized CPP films replace traditional aluminum foil, reducing weight by 37.5%, with an electrolyte corrosion resistance rate ≤0.05%/year, adapting to the soft packaging needs of Tesla 4680 batteries and improving battery energy density and safety.
(D) Agriculture and Construction: Cross-Industry Breakthroughs of Functional Materials
- Greenhouse Covering: 50μm metallized CPP reflective films with a reflectivity ≥85% reduce the temperature inside the greenhouse by 5°C in summer and reduce heat loss in winter. The strawberry yield is increased by 15%, and it has been applied on a large scale in the Shouguang vegetable base in Shandong.
- Building Energy-Saving Films: Metallized CPP films pasted on the inner side of glass have an infrared barrier rate ≥70%, reducing air conditioning energy consumption by more than 15%, in line with China’s “double carbon” goal, and suitable for commercial complexes and residential buildings.
III. Technical Advantages: The Core Competitiveness Driven by Innovation
(A) Full-Process Intelligent Manufacturing
- Vacuum Metallization Process: German Leybold winding vacuum coating machines are introduced, with the vacuum degree maintained below 10⁻³Pa, the aluminum layer deposition rate is 5-8nm/s, and the coating uniformity error ≤±2%, with an annual production capacity of 12,000 tons.
- Digital Quality Control System: The AI visual inspection system monitors film defects in real time, with a defect rate as low as 0.05%. The online thickness gauge is linked with the infrared spectrometer to ensure that each roll of film meets 100% of the indicators such as thickness and coating adhesion.
(B) Customized Solution Capability
- Flexible Specification Matching: The thickness ranges from 20-60μm, the width ranges from 200-1220mm, and various forms such as rolls and sheets are supported to meet the adaptation needs of different packaging equipment of customers.
- Functional Coating Development: Customized coatings such as anti-UV, anti-scratch, and easy-tear lines can be added. For example, anti-yellowing metallized films developed for the Southeast Asian market have a weather resistance of more than 5 years, solving the problem of packaging fading in tropical high-temperature and high-humidity environments.
(C) Global Service Network
- Rapid Response Mechanism: With three major production bases in China, Southeast Asia, and North America, it realizes 72-hour sample delivery and 15-day bulk shipment;
