French Fry Box Water-based Varnish Film: 0 Plasticizers Compostable
In the field of food packaging, environmental protection and sustainability have become important trends in the industry's development. The use of water-based varnish film technology combined with zero plasticizer compostable material is becoming a new solution to meet the dual standards of environmental protection and functional performance for the high-frequency packaging form of french fry boxes.
Water based varnish uses water as a solvent, which is non-toxic and odorless, completely avoiding the emission of volatile organic compounds (VOCs) in traditional oily varnish, and meets strict hygiene standards for food packaging. Its core advantage lies in its environmental friendliness - no plasticizer added, eliminating the potential contamination of food by harmful substances such as phthalates from the source; Functionality - By forming a film with polymer resin, the french fry box is endowed with water resistance, oil resistance, and wear resistance, effectively blocking external moisture and oil penetration, and extending the shelf life of food; Processability - supports online or offline coating, can be combined with paper, cellulose substrates, etc. to form a high barrier packaging structure, suitable for the lightweight requirements of french fry boxes.
Combined with the application of compostable materials, this solution further achieves an environmentally friendly closed-loop throughout the entire lifecycle of packaging. Taking TIPA's 312MET Premium film as an example, it uses a composite of bio based polymers and water-based adhesives, which can be completely decomposed into water, carbon dioxide, and biomass under industrial or household composting conditions. It has also passed international certifications such as EN13432 and ASTM D6400, ensuring no microplastic residue. Similarly, Metpack collaborated with BASF on Ezycompost coated paper for ecovio ® The 70 PS14H6 polymer coating replaces traditional PE coating and remains stable in boiling water at 100 ℃, while supporting home composting. The processing speed is 40% faster than PLA, providing a feasible path for the large-scale application of french fry boxes.
From the perspective of cost and efficiency, the water-based varnish coating process does not require heating and drying, with a production speed of up to 80 meters per minute, and equipment investment is lower than that of solvent based processes; Compostable materials can replace fossil resources with bio based materials, which may have a higher initial cost, but with policy subsidies and large-scale production, the long-term economic benefits are significant. For fast food brands, this plan not only responds to the global goal of reducing plastic waste, but also enhances consumers' sense of environmental identity through the "compostable" logo, helping brands differentiate and compete.
