1. What are the raw materials of disposable biodegradable meal boxes? And what’s the proportion of each material?

The common pulp molded meal boxes are made from 70-90% of bagasse and 10-30% of bamboo pulp. Different tableware should adjust the proportion of each material according to the different needs of shape, angle, hardness, or toughness. This kind of product is totally made from plant fiber without adding PP, PET, etc.

2. How do pulp molded containers realize waterproof and oilproof?

For pulp molded products, they will always add some food-grade additives to realize waterproof and oil proof, such as 1-2.5% of waterproofing agent and 0.5-0.8% of oil proofing agent. This kind of product can always effectively prevent water and oil from leaking over 30mins. For some special requirements, there are also special solutions to increase the temperature and time.

3. Does biodegradable tableware have PFAS?

Most of the oil-proofing agents in the plant fiber tableware on the market have PFAS, while waterproof but no oilproof tableware doesn’t have PFAS.

If you want tableware waterproof and oilproof without PFAS, the best alternative solution is filming. PBAT is one of the most popular films in pulp molded tableware. This kind of film can be biodegraded.

Products with films can better maintain the temperature, and reduce the stickiness between rice and container, which can, to a large extent, reduce the use of water and oil proofing agents.

4. How long will a pulp molded tableware be totally biodegraded?

Under the condition without any industrial measures, it usually takes 45-90 days for pulp molded tableware to be totally biodegraded under natural conditions without releasing harmful substances, which will not cause damage to terrestrial biotas and marine organisms.

5. Can pulp molded containers be used in the microwave and refrigerator? What’s the temperature range?

Pulp molded containers are microwave and refrigerator safe, which can resist a temperature of up to 200℃, and frozen to -20℃.

6. What standards should pulp molded containers meet?

Pulp molded containers should meet the standard of China Pulp Molded Tableware quality control standards, FDA, LFGB, and any other international standardized inspection standards.

7. Are the raw materials of white biodegradable food containers bleached? What bleach to use?

Unbleached plant fiber pulp is yellow due to a small amount of lignin and colored impurities, and the fiber is more solid than bleached one; the semi-bleached pulp molded product is pale yellow because it has lots of pentosane; these kinds of colors are usually called “Natural Color”. The bleached pulp product is white and soft, while the fiber strength is lower than the unbleached one. Normally, we often use hydrogen peroxide to bleach.
