CPET stands for crystallized polyethylene terephthalate. It’s a popular choice for food packaging thanks to its strength and resistance to heat. "Why should I choose CPET shrink film?" you might ask. It provides excellent barrier properties, ensuring your food stays fresh longer.

What are you packaging? If it’s food, you need to consider several factors, such as moisture and temperature. "I’m packaging frozen meals. Should I use CPET?" Absolutely! CPET shrink film is perfect for items that require heating.

2. Consider the Size

Measure your products carefully. "What if my product is irregularly shaped?" No worries! CPET shrink film can conform to various shapes. Just ensure your film is wide enough to wrap around your items properly.

3. Check for Compatibility

4. Think About Shelf Life

Longer shelf life means happier customers. "Does CPET really help with this?" Yes! Thanks to its excellent barrier properties, CPET shrink film keeps out moisture and oxygen, extending the freshness of the product.

5. Evaluate Heat Resistance

If you plan to heat your products in the film, heat resistance is crucial. "What’s the ideal temperature for CPET shrink film?" Most CPET films can withstand temperatures up to 190°C (374°F). That’s perfect for microwaving or oven-cooking meals.

8. pricing

Budget considerations are essential. "How do I know if I’m getting a good deal?" Compare prices from different suppliers and consider the quality of the film. Sometimes, investing a little more leads to better protection and longer shelf life.
