Clear PP sheet for vacuum forming

Clear PP sheet (polypropylene sheet) is a plastic sheet with high transparency produced by special process using polypropylene material. Polypropylene is a lightweight, tough and chemically resistant thermoplastic polymer. Through fine formulation and process control, PP sheet can achieve good transparency while maintaining its excellent physical and chemical properties. The transparency of clear PP sheet makes it particularly popular in food, medicine and other packaging applications that need to display products.

Characteristics of clear PP sheet

High transparency: By optimizing the production process, clear PP sheet can show near-glass transparency, which is convenient for consumers to directly see the product in the package, thereby enhancing the visual appeal of the package.

Lightweight: PP sheet has a low density, usually around 0.90 g/cm³, which can effectively reduce the weight of the package and reduce transportation costs.

Excellent heat resistance: Clear PP sheet can maintain its stability at higher temperatures and will not deform. Suitable for food packaging that requires high-temperature sterilization, such as microwave heating containers.

Chemical corrosion resistance: PP sheet has strong chemical corrosion resistance and can resist the erosion of various chemical solvents, oils, acids and alkalis to ensure the safety of the packaging contents.

High strength and toughness: Clear PP sheet has good impact resistance and toughness. Even under low temperature conditions, it can still maintain excellent physical properties and is not easy to break.

Recyclability: PP sheet is a recyclable plastic that meets environmental protection requirements. In the context of global sustainable development, clear PP sheet is more widely used.

Low water vapor permeability: PP sheet has low water vapor permeability, which can effectively block water vapor and keep the food in the package dry and fresh.

Advantages of clear PP sheet

Food grade safety: Clear PP sheet meets the safety standards of food contact materials and does not contain harmful substances such as bisphenol A, plasticizers, etc. Therefore, it is widely used in food packaging to ensure food health and safety.

Easy to process and shape: Transparent PP sheet has excellent thermoforming properties and can be processed into packaging trays or containers of various shapes through vacuum forming, compression forming and other processes to meet different packaging needs.

High economic benefits: PP materials have a more economical production cost compared to other high-transparency plastics (such as PET and PC). While meeting performance requirements, it reduces production and material costs for enterprises.

Good transparent display effect: Due to its high transparency, clear PP sheet packaging is not only functional, but also can enhance the display effect of products, especially in packaging that needs to display the appearance of food or goods, such as frozen food, cakes, and fruit and vegetable packaging.

Strong environmental protection: Transparent PP sheets have excellent recyclability and degradability. After use, they can be processed into plastic products again, reducing environmental pollution.

Good low-temperature resistance: Clear PP sheets are not easy to become brittle at low temperatures, suitable for frozen food packaging, and can be directly stored in a refrigerator or refrigerator.

Application areas

Food packaging: Clear PP sheets are often used in food trays, box lids, containers and other packaging. Its transparency allows consumers to easily view the food in the package, especially suitable for packaging of fresh food, frozen food, snacks, cakes, etc.

Drug and medical device packaging: Transparent PP sheets are widely used in the packaging of drugs and medical devices, providing a hygienic and safe packaging environment. At the same time, transparency also facilitates the inspection of product status.

Electronic product packaging: Transparent PP sheets can be used for the packaging of electronic products, especially those that require dust and moisture resistance. The low water vapor permeability of PP sheets helps protect electronic products.

Daily necessities packaging: Clear PP sheets are also commonly used in various daily necessities packaging, such as cosmetic containers, household plastic product packaging boxes, etc., providing good display effects and protective performance.

Industrial product packaging: Industrial parts and hardware products can also be packaged with Clear PP sheets, which are not only beautiful, but also can reduce the possibility of surface scratches and breakage.

Comparison with other materials

In comparison with other transparent materials (such as PET, PC, etc.), clear PP sheets have shown some unique advantages:

Compared with PET: Clear PP sheets have better heat resistance, especially in microwave heating applications. And the cost of PP materials is usually lower than PET, so in cost-sensitive applications, PP sheets are a more cost-effective choice.

Compared with PC: Although the transparency of PC (polycarbonate) sheet may be slightly better than that of PP sheet, PP sheet is more food-safe, does not contain potentially harmful substances such as bisphenol A, and the cost of PP is much lower than that of PC, making it suitable for large-scale packaging applications.
