China PP90-360U blister cup, heat-resistant and printable Manufacturers, Factory

Food-grade PP plastic bowls made from high-quality polypropylene are durable, microwave-safe up to 100°C, and resistant to corrosion from acidic and alkaline substances such as lemon juice and baking soda solutions. They offer excellent sealing for long-term storage, making them ideal for preserving freshness in refrigerators and freezers, although they have weak low-temperature impact resistance. This limitation can be mitigated by incorporating fillers like glass fibers, which enhance their structural integrity at lower temperatures. Certified by the FDA, these bowls are non-toxic, ensuring safety for food contact, and are also recyclable, contributing to environmental sustainability by reducing waste. Their lightweight nature and versatility make them suitable for various culinary applications, from everyday meal prep to professional kitchen use.

Product Description

Product Advantages

Polypropylene (PP) meets stringent FDA and EU food safety standards, ensuring its non-toxic nature and chemical inertness, which makes it safe for direct contact with food products.

This material boasts exceptional mechanical properties, including high tensile strength and impact resistance, alongside impressive temperature tolerance ranging from -20°C to 135°C, and robust moisture-proof characteristics, all of which make it an optimal choice for food packaging applications.

PP is also highly recyclable, contributing to environmental sustainability, and remains lightweight, enhancing convenience in transportation and storage. Its versatility allows it to be utilized across various forms such as films, containers, trays, and specialized medical/pharmaceutical packaging.

The key benefits of using PP include its remarkable durability, which ensures long-lasting performance, heat resistance, enabling it to withstand microwave and dishwasher use, and aesthetic appeal, as it can be easily molded into attractive and functional designs.

Additionally, PP's low permeability to gases and liquids further enhances its suitability for preserving the freshness and quality of packaged foods.

Product Features

The PP lid excels in microwave heating due to its heat resistance, which prevents deformation and melting, ensuring durability and safety during high-temperature operations. This lid also effectively prevents odor absorption, maintaining the original aroma and flavor of the food. By being non-reactive with food, it preserves the nutritional value, making it a health-conscious choice for meal preparation. Key features include:

  • Retains steam for efficient cooking, ensuring even heat distribution and optimal moisture retention.
  • Compatible with microwave-safe containers, allowing for versatile use with various types of cookware.
  • Transparent for easy monitoring without opening the door, providing convenience and peace of mind by allowing users to check on their food's progress without interrupting the cooking process.

Product Application

Polypropylene (PP) is a versatile thermoplastic polymer used in various sectors due to its lightweight, chemical resistance, and processing properties. Its semi-crystalline structure allows it to withstand high temperatures and resist moisture, making it ideal for demanding environments.

Key applications include:

  • Industrial containers: Benefit from its durability and ability to maintain shape under heavy loads.
  • Medical instruments: Non-reactive nature ensures safety and sterility.
  • Food packaging: Transparency and barrier properties keep contents fresh and protected.
  • Automotive parts: Strength and flexibility contribute to vehicle performance and safety.
  • Home appliances: Heat resistance and ease of cleaning for items like dishwasher-safe cutlery.
