Waterproof and oil resistant, no need for plastic coating for french fries boxes

Have you ever noticed that seemingly ordinary packaging box while enjoying crispy French fries? Traditional paper boxes are mostly covered with a thin layer of plastic film for waterproofing and oil resistance. Although this "invisible raincoat" brings convenience, it also imposes a heavy burden on the earth - paper plastic composite materials are difficult to recycle and are mostly burned or buried in the end.
Nowadays, a quietly emerging green revolution is changing this situation. The waterproof and oil resistant french fries box, which does not require plastic coating, has moved from concept to reality.
The core technology of this new environmentally friendly french fries box lies in "replacing plastic with paper" or "replacing plastic with plants". It completely abandons the traditional PE (polyethylene) plastic coating and adopts two main technological paths: one is water-based coating technology, which uses water as a dispersing medium to evenly adhere special resins to the surface of paper fibers, forming a dense waterproof and oil proof layer without leaving any plastic film; The second is plant fiber molding technology, which directly utilizes natural plant fibers such as sugarcane bagasse, bamboo pulp, and reed. Through special processes, food contact compliant waterproof and oil resistant additives are added during the pulping process, and then formed by high-temperature hot pressing.
The performance of these innovative materials is surprising. It combines various plant celluloses and achieves excellent waterproof and oil resistant effects without any chemical coating. It can even withstand high temperatures of 220 degrees Celsius and can be directly placed in a microwave or oven for reheating. 'Plastic free paper' is also waterproof, oil resistant, and can be heat sealed. Its decomposition time after disposal is much shorter than traditional coated paper, and it does not pose a risk of microplastics.
From plastic coated boxes covered in oil stains to now clean and recyclable plastic free french fries boxes, behind this small step of transformation is the fulfillment of technology's commitment to environmental protection and the wisdom of reconciliation between humans and nature.
