Guangdong Guowei Guanli New Materials : Food Packaging Paper Bag Upgrade, Safety and Environmental Protection

At the moment when the concept of green consumption is deeply rooted in the hearts of the people, the safety and environmental protection of Food Packaging has become the focus of market attention. Guangdong Guowei Guanli New Material Co., Ltd.has comprehensively upgraded Food Packaging Paper Bags by virtue of years of technical accumulation in the field of packaging materials, from raw material screening to production process innovation, achieving double breakthroughs in safety performance and environmental protection standards, and providing more reliable Packaging Solutions for baking, fast food, pet food and other fields.​

 

The core of this upgrade lies in the innovative application of raw materials. The company abandoned the traditional bleaching process paper and used food-grade kraft paper made of 100 % native wood pulp. The SGS test showed that the content of heavy metals such as lead and arsenic was less than 0.01 mg / kg, and the test result of fluorescent whitening agent was zero, which fully met the EU EFSA food contact material standard. This paper has excellent moisture resistance while maintaining good stiffness. By adding plant-based waterproof coating, the moisture permeability is controlled within 5g / ( m2 · 24h ), which solves the pain point that traditional paper bags are easy to absorb moisture. It is especially suitable for pastry bags for cookies, Paper Bread Bags and other baking packaging scenarios that need long-term preservation.

 

In the production process, China has introduced a fully automatic dust-free production line to realize the whole process of aseptic operation from paper cutting to bag molding. In view of the special needs of take away packaging, the upgraded food packaging paper bag has an oil-resistant layer design. The food-grade silicone oil paper composite process can withstand 120 °C high temperature oil immersion without leakage, and the tear strength is increased by 40 %, which solves the problem of bag damage during takeaway delivery. At the same time, the pocket is designed with easy tearing line and self-adhesive seal, which can be opened and closed by consumers with one hand, so as to ensure the sealing and improve the convenience of use.

The optimization of subdivided product series is more targeted. The cookie snack bag adopts the window-opening design, and the transparent part adopts the degradable bio-based film, which is not only convenient for displaying the product form, but also can be degraded naturally with the main body of the paper bag. The bread paper bag adds air holes on both sides of the bag body, cooperates with the anti-ironing handle, and takes into account the freshness of the bread and the safety of carrying. It is worth noting that these upgraded food packaging paper bags can be completely degraded within 3 months in the natural environment after they are discarded. Compared with traditional plastic packaging, carbon emissions are reduced by 72 %, and the environmental protection closed loop of ' from nature, to nature ' is truly realized.​

 

In addition to the food field, China 's paper bag upgrade technology has also extended to pet food packaging. On the basis of moisture-proof performance, the dog food paper bag packaging has added a one-way exhaust valve, which solves the problem that pet food is easy to be wet and agglomerated after opening. At the same time, the bag body adopts puncture-resistant materials, which can withstand pet bites without damage, taking into account safety and durability. 

 

Guangdong Guowei Guanli New Material Co., Ltd.has always been based on the concept of " safety as the basis and environmental protection as the soul. " This upgrade of food packaging paper bags has not only passed international certifications such as FDA and LFGB, but also established a whole chain quality control system from raw material traceability to finished product testing. In the future, the company will continue to explore the application of plant-based materials and plan to launch edible-grade coated paper bags to provide more innovative solutions for the green upgrading of the food packaging industry.
