Plastic bags and nozzles made from 100% recyclable materials come out

[China Packaging Network News] More and more companies are promoting the development of sustainable packaging, one of which is bag fittings / welding nozzle manufacturer HQC (Oswego, Illinois, USA), the company has The moldability and insertion compatibility of two 100% recyclable materials are tested, one of which is industrial grade and the other is Ecovision, the eco-primary resin of Envision Plastics.

The eco-main resin has received support from the U.S. Food and Drug Administration, allowing it to be used for food packaging. It is a safe, post-consumer, high-density polyethylene (HDPE) resin that does not contain BPA, phthalates, heavy metals, or allergens and is 78% less greenhouse gases than primary resins, and does not require the addition of colorants.

HQC has been experimenting with 100% eco-main resins in the production of sustainable pouches/welding nozzles, and has experimented with different ratios of eco-primary resins to native resins. The results are very optimistic. Improvements in the molding process and sealing strips make eco-primary resins comparable to certain 100% primary petroleum-based materials. The rigorous testing of HQC in the past two years also included batch quantities of mixed materials to ensure that the multi-source materials were sufficiently consistent to prevent quality problems in the production process.

Currently, HQC is working with a large film company to make a seal with a burglarproof tape. The purpose is to use the cover and accessories made of eco-resin to insert the bag fitting/welding tip into the full polyethylene bag.

HQC is testing plant-based materials mixed with eco-primary resins. Making caps, accessories, and bags from the mix will make the product completely sustainable and recyclable without having to sort caps and bags. HQC specializes in plastic spoons, custom molded CT seals, and pouches for the food and beverage, personal care, medical device and flexible packaging markets.

Through testing consistency and performance, HQC also discovered process changes, increased seal strength, and reduced cycle times. It also determines the advantages through the seal strip design. In some cases, even with a standard membrane structure, some adjustments will increase the mating seal strength by more than seven times the original pounds per square inch.

Blaise Pasternak, president of HQC, said: “The production of bag fittings/tips for HQC industrial equipment is an easy part, but it is a bit difficult to adjust the products used in films and bags. of."

The real challenge is testing equipment: how does it work when inserted? What are its limitations? What happens during the insertion process? These are questions that need to be answered before selecting the assembly materials and using them in production. HQC will help companies stand out in this area, whether they are just getting started or are already making progress.
