Food-grade natural PP sheet for positive press thermoforming
White PP low-temperature-resistant sheet has the following properties:
Non-toxic and odorless: It meets food packaging hygiene standards and can come into direct contact with food without posing a risk to human health, ensuring the food safety of quick-frozen dumplings.
High mechanical strength: It possesses high tensile strength, flexural strength, and hardness, capable of withstanding certain pressure and impact forces, effectively protecting dumplings from damage during storage, transportation, and distribution.
Excellent barrier properties: It offers a certain barrier capability to oxygen and water vapor, slowing oxidation and water loss in dumplings, preserving their freshness and flavor, and extending their shelf life.
Excellent low-temperature resistance: Specially modified, it maintains excellent flexibility and mechanical properties in low-temperature environments (typically -30°C to -40°C), preventing brittle cracking and ensuring the proper use of blister trays in frozen conditions.
White PP low-temperature-resistant sheet has excellent barrier properties, which are crucial for extending the shelf life of dumplings and reducing the effects of moisture and oxygen on them. During dumpling storage, water loss can cause the wrappers to dry out and crack, affecting their taste and quality. The presence of oxygen accelerates oxidation of the filling, degrading the flavor and potentially allowing microbial growth, shortening the dumpling's shelf life.
White PP cold-resistant sheet material offers excellent processability, enabling it to meet the demands of various shapes, specifications, and designs for frozen dumpling blister trays. Due to its excellent thermoplastic properties, the sheet material quickly softens upon heating during the blister forming process and can be molded into various shapes through the use of molds.
The blister forming process is simple and efficient, offering high production efficiency. Molds can be quickly adjusted to meet market and customer requirements, enabling the production of frozen dumpling blister trays of varying sizes, shapes, and structures. For example, to accommodate the unique shapes and packaging styles of different dumpling brands, we can produce both standard rectangular blister trays and trays with specialized grooves and dividers to better secure the dumplings and prevent them from shifting or colliding during transportation and storage.
