PP anti-freeze plastic sheet for frozen product packaging

What is PP anti-freeze plastic sheet?

PP anti-freeze plastic sheet, also known as low-temperature rigid polypropylene sheet, is a modified plastic made of polypropylene (PP) with good low-temperature performance and can withstand use under freezing conditions. It is a commonly used frozen food packaging material with the following characteristics:

• Low temperature resistance: PP anti-freeze plastic sheet can be used in an environment below -40℃ without embrittlement or breakage.
• Freeze resistance: PP anti-freeze plastic sheet can withstand temperature changes during freezing and thawing without deformation, warping and other problems.
• High transparency: PP anti-freeze plastic sheet has good transparency, which can clearly show the appearance of the product and improve the visual effect of the product.
• Excellent processing performance: PP anti-freeze plastic sheet is easy to process and can be processed by injection molding, extrusion molding, blow molding and other processing methods.
• Environmental protection: PP anti-freeze plastic sheet is a recyclable material that meets environmental protection requirements.

Advantages of PP anti-freeze plastic sheet

Effective protection of frozen food: PP anti-freeze plastic sheet can effectively protect frozen food from low temperature damage, water loss, bacterial contamination, etc., and extend the shelf life of food.

Improve the aesthetics of product packaging: PP anti-freeze plastic sheet has good transparency, which can clearly show the appearance of the product and improve the aesthetics of product packaging.

Reduce packaging costs: PP anti-freeze plastic sheet is inexpensive and easy to process and shape, which can reduce packaging costs.

Meet environmental protection requirements: PP anti-freeze plastic sheet is a recyclable material that meets environmental protection requirements.

Application of PP anti-freeze plastic sheet

PP anti-freeze plastic sheet is widely used in the field of frozen food packaging, mainly used to make the following types of packaging boxes:

Frozen food packaging box: used to package frozen foods such as ice cream, quick-frozen food, meat, and aquatic products.

Thermoformed blister packaging box: used to package frozen fruits, vegetables, cakes and other frozen foods.

FAQ

Q: What is the difference between PP anti-freeze plastic sheet and ordinary PP plastic sheet?

A: The main difference between PP anti-freeze plastic sheet and ordinary PP plastic sheet is low temperature resistance and anti-freeze. PP anti-freeze plastic sheets have been specially modified to maintain good mechanical properties and dimensional stability in low-temperature environments, while ordinary PP plastic sheets are prone to brittleness and fracture in low-temperature environments.

Q: Can PP anti-freeze plastic sheets replace other types of frozen food packaging materials?

A: PP anti-freeze plastic sheets can replace some types of frozen food packaging materials, such as cardboard, cartons, etc. However, for some frozen foods that require high packaging strength, such as metal cans, PP anti-freeze plastic sheets may not be completely replaced.

Q: What is the future development prospect of PP anti-freeze plastic sheets?

A: With the development of the frozen food industry, the demand for frozen food packaging materials will continue to grow. PP anti-freeze plastic sheets will be more widely used in the field of frozen food packaging with its excellent low-temperature resistance, anti-freeze, and environmental protection.

Q: What is the low-temperature resistance of PP anti-freeze plastic sheets?

A: PP anti-freeze plastic sheets can be used for a long time in low-temperature environments below -40°C without brittle fracture.

Q: What is the impact resistance of PP anti-freeze plastic sheets?
A: PP anti-freeze plastic sheet has good impact resistance and can withstand greater impact and collision force.

Q: How is the transparency of PP anti-freeze plastic sheet?

A: PP anti-freeze plastic sheet has good transparency and can clearly show the appearance of the product.

Q: How is the processing performance of PP anti-freeze plastic sheet?

A: PP anti-freeze plastic sheet is easy to process by injection molding, extrusion molding, blow molding and other processing methods, and can be processed into products of various shapes.
