Pet plastic sheet roll for frozen food packaging refers to a continuous roll of plastic sheet made from PET (polyethylene terephthalate) material that is specifically designed for packaging frozen food products. It is a versatile and widely used packaging solution in the food industry.
The PET plastic sheet roll is typically transparent and comes in various thicknesses and widths, allowing it to be easily customized and cut into the desired size for packaging different types of frozen food items. The roll format enables efficient and flexible packaging production, as it can be unwound, formed, and sealed using appropriate packaging machinery.
Origin: Shanghai, China
Barrier material: Pet plastic thermoforming sheet
Processing methods: Lamination/Multilayer co-extrusion
Color: Transparent/Custom color
PET plastic sheet rolls for frozen food packaging offer several important features and benefits:
1. Temperature resistance: PET plastic is resistant to low temperatures, making it suitable for freezing applications. It maintains its integrity and does not become brittle or crack under freezing conditions.
2. Barrier properties: PET plastic provides a barrier against moisture, oxygen, and other gases, protecting frozen food products from freezer burn, dehydration, and contamination. It helps to maintain the quality, taste, and freshness of the food during storage and transportation.
3. Transparency: The transparent nature of PET plastic allows consumers to see the contents of the packaging, enabling them to assess the product’s quality and appearance before purchase.
4. Strength and durability: PET plastic sheet is known for its strength and resistance to tearing, puncturing, and impact, ensuring the packaging can withstand the rigors of handling, transportation, and storage.
5. Food safety: PET plastic sheet is widely recognized as a safe and approved material for food contact. It meets regulatory requirements and is suitable for packaging frozen food items while maintaining their safety and quality.
PET plastic sheet rolls for frozen food packaging are commonly used for a wide range of frozen food products, including frozen fruits, vegetables, meats, seafood, prepared meals, and desserts.
1. PET sheet has good mechanical properties, impact strength is 3 to 5 times that of other sheets, and good folding resistance.
2. Resistance to oil, fat, dilute acid, dilute alkali, and most solvents.
3. It has excellent resistance to high and low temperatures. It can be used for a long time within a temperature range of 120°C, and can withstand high temperatures of 150°C and low temperatures of -70°C in short-term use, and has little effect on its mechanical properties at high and low temperatures.
4. The gas and water vapor permeability is low, and it has excellent gas, water, oil and odor resistance.
5. High transparency, can block ultraviolet rays and good gloss.
6. Non-toxic, tasteless, good hygiene and safety, and can be directly used for food packaging.
It is important to note that proper handling, storage, and adherence to food safety guidelines are essential to ensure the safety and quality of the packaged frozen food products.
Proper maintenance of PET plastic sheet rolls for frozen food packaging is crucial to ensure the quality and effectiveness of the packaging. Here are some key maintenance practices to consider:
- Storage: Store PET plastic sheet rolls in a clean, dry, and well-ventilated area, away from direct sunlight and extreme temperatures. Ideally, the storage area should have controlled humidity to prevent moisture absorption by the sheets.
- Handling: Handle PET plastic sheet rolls with clean hands or wear gloves to prevent contamination. Avoid touching the inner surface of the sheet, as it will come into direct contact with the food.
- Cleaning: Before using PET plastic sheet rolls, ensure they are free from dirt, dust, or any other contaminants. Clean the working surface and equipment that will come into contact with the sheets to maintain hygiene standards.
- Inspection: Regularly inspect the PET plastic sheet rolls for any signs of damage, such as tears, punctures, or degradation. Damaged sheets should not be used for packaging, as they can compromise the integrity and safety of the food.
- Usage guidelines: Follow the manufacturer’s guidelines regarding the recommended storage conditions, temperature limits, and handling instructions for the specific PET plastic sheet rolls you are using. Adhering to these guidelines will help ensure the optimal performance of the packaging.
- Proper sealing: Ensure that the PET plastic sheet rolls are properly sealed to maintain the integrity of the packaging and prevent air or moisture ingress. Use appropriate sealing methods, such as heat sealing or adhesive tape, to create a secure and airtight seal.
- FIFO (First-In, First-Out): Follow the FIFO principle when using PET plastic sheet rolls. Use the oldest rolls first to prevent them from sitting in storage for too long, which could potentially affect their quality.
- Regulatory compliance: Ensure compliance with relevant food safety regulations, such as those regarding direct food contact materials. Use PET plastic sheet rolls that are approved for food contact and meet the necessary regulatory requirements.
By following these maintenance practices, you can help ensure that PET plastic sheet rolls for frozen food packaging remain in optimal condition, maintaining the quality, safety, and freshness of the packaged food products.
