EspañolIf you're a purchasing professional in the food packaging industry and considering adding a double color blown film machine to your production line—whether for snack packaging, fresh food packaging, or frozen food bags.
Choose the right machine for your food packaging needs
Frankly, not all double color blown film machine are created equal. The machine you choose must be a perfect match for the food packaging you're producing. For example, if you're packaging fresh produce, you need a thin, breathable, brightly colored film—for instance, organic labels require green. Frozen food bags, on the other hand, require a thick, puncture-resistant film that can withstand high-temperature sealing.
We conducted a three-month comparative test on five of the most popular machines on the market, and here are our findings: The DeXiang double color blown film machine excels in thickness uniformity—with a tolerance of only ±2%, compared to the industry average of ±5%. Its color retention is also far superior to other machines: it doesn't fade even after more than 1000 freeze-thaw cycles. All tests were conducted according to GB/T 17313-2009 standards.
Key considerations when comparing machines include: food-grade blown film, a double color structure suitable for food packaging, and consistent thickness control. The machine's output ranges from 30-60 kg/hour and it can process LDPE and HDPE.
Ensuring compliance with food safety and international certification standards
Food packaging demands utmost care. Failure to meet safety standards can lead to product recalls, fines, and even exclusion from key markets. The good news is: DeXiang's double color blown film machine is fully prepared to meet all your needs.
It is CE and ISO 22000 certified. All components in contact with the material are food-grade—free of any harmful plasticizers or heavy metals, fully compliant with FDA and EU food contact requirements. Unlike cheap machines that may release harmful chemicals, DeXiang uses a precision heating system to prevent material degradation, ensuring your film is safe for direct food contact.
Here's a real-world example from a frozen food brand
After switching to DeXiang products, their packaging successfully passed the EU food safety audit with zero defects. Within just six months, customer complaints about packaging odors decreased by 82%.
Certification is not just theoretical; it's a real competitive advantage. Optimizing operations, improving efficiency, and saving costs—many buyers focus only on the machine itself, neglecting setup and operation. However, some small adjustments can easily reduce material waste by 15-20%.
DeXiang offers customized services, including on-site training for your team. Their technicians will guide your operators on how to fine-tune air pressure and temperature to avoid wrinkling and fading—these two issues alone can cause approximately 10% of raw material waste on a poorly set production line.
Another key advantage: DeXiang's integrated control system allows you to remotely monitor color ratios and film thickness, significantly reducing human error.
Ensuring long-term reliability with after-sales support
In the food packaging industry, downtime equals lost money. Every minute the production line is down directly impacts your profits. Therefore, you need a supplier that truly provides after-sales support.
DeXiang offers: 24/7 technical support, a 3-year warranty, on-site repair within 48 hours for domestic customers, and within 72 hours for overseas customers.
