Background

A well-known frozen food company mainly produces quick-frozen foods such as dumplings and wontons. With the continuous expansion of market demand, the company urgently needs a packaging solution that can ensure food safety and maintain the integrity of the packaging box in a low-temperature environment. Traditional packaging materials are prone to brittle cracking and deformation under freezing conditions, affecting product appearance and transportation safety. To this end, the company began to look for an anti-freeze packaging material designed specifically for low-temperature environments.

Challenge

• Insufficient low-temperature adaptability: Ordinary PP sheets are prone to cracking or loss of toughness below -20°C and cannot withstand low-temperature environments for a long time.
• High thermoforming requirements: The packaging box needs to be processed through a thermoforming process, requiring the material to soften evenly at high temperatures and to be quickly fixed after forming.
• Food-grade safety: The packaging material must meet food contact safety standards to ensure consumer health.

Solution

In order to solve the above problems, the company introduced the anti-freeze PP plastic sheet rolls we provided. The product has the following characteristics:

• Excellent anti-freezing performance: The special formula ensures that it still maintains good toughness at low temperatures and will not crack.
• Excellent thermoforming performance: The material can quickly and evenly soften after heating, and with the vacuum blister process, it ensures that the molding effect is fine and the size is stable.
• Food grade certification: The raw materials are strictly tested to ensure compliance with food safety standards.

In actual applications, our anti-freezing PP sheet successfully produces frozen dumpling packaging boxes through thermoforming. The box body is transparent and beautiful, and can withstand long-term frozen transportation.

Implementation effect

• Improved product quality: The new packaging box is resistant to low temperatures and impacts, reducing the breakage rate during transportation.
• Improved production efficiency: The optimized thermoforming process speeds up the molding speed of the packaging box, and the hourly production volume increases by about 20%.
• Enhanced customer satisfaction: The food has a beautiful appearance and the packaging is safe and stable, which has won high praise from consumers and wholesalers.

Conclusion

By adopting our anti-freezing PP plastic sheet, the customer successfully solved the problem of traditional packaging materials in low temperature environments, which not only improved product quality, but also optimized the production process, and won a market competitive advantage for the company.
