TopScreen biowax-based barrier coatings are the solution to consumer demand for paraffin-free, environmentally friendly, paper packaging. Derived from vegetable oils, these functional biowax barrier coatings are free from harmful mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH), making them an excellent choice for food-grade paper packaging applications. And, paper and board treated with TopScreen biowax barrier coatings are repulpabable, recyclable and compostable, making the coatings a better environmental choice than paraffin-based wax coatings.
In addition to providing superior oil, grease and water resistance and control of water vapor transmission rate, TopScreen biowax barrier coatings offer many appealing features and benefits. For example, they:
Market demand for environmentally sustainable paper packaging has grown over the years, spurring paper and board producers to eliminate their use of paraffin-based barrier coatings. TopScreen biowax-based barrier coatings are derived from renewable resources, which satisfy consumer demand for eco-friendly products while helping papermakers comply with environmental regulations.
Food packaging must provide effective oil, grease and water resistance and water vapor transmission rate without exposing consumers to unsafe chemicals. TopScreen biowax barrier coatings deliver superior performance and are free from harmful chemicals, making them an ideal choice for a variety of food packaging applications, including:
TopScreen biowax-based barrier coatings can be applied on existing wax applicators, including roll, curtain and cascade coaters. The coatings are typically applied at temperatures between 80 and 160 °C, depending upon the grade, and can be adapted to specific requirements for water repellency, fat resistance, water vapor transmission rate, gloss, release properties and viscosity.
