Publish Time: 2025-01-27
PC optical film thickness plays an important role in the field of food packaging with its excellent impact resistance. The characteristics of this material enable it to effectively protect food and ensure its safety and integrity during transportation and storage.1. High impact resistanceMaterial characteristics: PC is a thermoplastic known for its extremely high impact resistance. Compared with traditional glass or some plastics, PC film can withstand greater external force impact without breaking.Protect food: In food packaging, especially during transportation, the packaging may be subjected to vibration, falling or other mechanical shocks. The high impact resistance of PC optical film thickness can prevent accidental damage to the packaging, thereby protecting the food from contamination and damage.2. Transparency and optical propertiesClear vision: PC optical film thickness has excellent transparency and optical properties, making the food in the package clearly visible, attracting consumers while also facilitating the inspection of the quality and freshness of the food.Keep fresh: Transparent packaging helps consumers assess the freshness of food, such as the color of vegetables and the glossiness of fruits, so as to make more informed purchasing decisions.3. Heat and cold resistanceTemperature adaptability: PC optical film thickness can withstand a wide range of temperatures, from very low freezing temperatures to higher heating temperatures. This makes it suitable for a variety of food storage conditions, including refrigeration and freezing.Maintaining food quality: Maintaining structural stability at different temperatures ensures that the packaging will not deform or break due to temperature changes, thereby protecting the quality of food.4. Lightweight and durableWeight reduction: Compared with glass or other heavy materials, PC film is lighter, which helps to reduce the overall weight of the packaging and reduce transportation costs.Extended service life: The durability of PC film means that the packaging can withstand multiple uses and treatments, reducing waste generation and complying with the principles of sustainable development.5. Sealing and barrier propertiesSealing integrity: PC optical film thickness can be combined with other material layers to form a multi-layer structure to enhance the sealing performance of the packaging, prevent air, moisture and odor penetration, and extend the shelf life of food.Blocking oxygen and moisture: By compounding different barrier layers, PC film can help prevent oxygen and moisture from entering the packaging, slowing down food oxidation and water loss, and maintaining the freshness and taste of food.6. SafetyNon-toxic: Food contact grade PC optical film thickness undergoes rigorous safety testing to ensure that it does not contain substances harmful to the human body and meets food safety standards.Recyclability: Many PC film products are recyclable, which helps reduce environmental impact and promote a circular economy.7. Design flexibilityDiversified design: PC optical film thickness can undergo a variety of processing, such as thermoforming, printing and decoration, making the packaging design more diverse and personalized to meet the market needs of different food brands.8. Application casesBeverage and water bottles: PC optical film thickness is often used to make transparent beverage and water bottles, providing good impact protection and visual appeal.Fruit and vegetable trays: In supermarkets, fruits and vegetables are often packaged in transparent trays made of PC film, which protects the products and facilitates display.Ready-to-eat lunch boxes: Lunch boxes made of PC film can withstand microwave heating and protect food from being squeezed or damaged during transportation.PC optical film thickness provides comprehensive protection for food packaging through its excellent impact resistance, transparency, temperature resistance, sealing and design flexibility. It not only ensures the safety of food during transportation and storage, but also enhances the attractiveness of the product and the consumer's purchasing experience.
