According to China's GB9685 "Standards for Additives for Food Contact Materials and Products," the use of non-biodegradable disposable plastic straws is prohibited in the entire catering industry nationwide by the end of 2020. Under the ban on plastic straws, paper straws, with their advantages of being environmentally friendly and low-cost, have become the mainstream choice in the market.
Advantages of VAE emulsion
Due to its strong adhesion to various substrates, excellent thermal resistance, superior film-forming properties, and wide applicability in formulations, VAE emulsion is frequently used in the production of various paper glues and packaging glues, many of which are used for food packaging.
based on this, Wacker has developed a food-grade VAE emulsion, VINNAPAS, that complies with GB9685 standards.®Weinai Real®EP 775. Using VINNAPAS®Weinai Real®EP 775-produced paper straws exhibit high stiffness, low odor, good general applicability, wide applicability, and excellent storage stability.
All raw materials and additives used in the production of this emulsion are selected from the list specified in GB9685, and they also meet all relevant restrictions specified in the standard, such as dosage, residue limits, and specific migration rates.
Highly water-resistant
Furthermore, paper straws made with Vak's new VAE emulsion exhibit excellent water resistance. They do not warp or curl even after being immersed in 90°C water for 3 hours.
Vak's new food-grade VAE emulsion can be used not only for paper straws but also for the production and packaging of food packaging boxes, bags, and cardboard boxes, as well as for paper, cardboard, and paper cups that come into contact with food and beverages.
