Is there anything else added to the biodegradable disposable tableware product?

May 3, 2025

At present, most of the oil repellents in plant fiber tableware on the market are fluorine-containing, and water- and oil-proof tableware is fluorine-free.

If the biodegradable tableware is required to be fluorine-free and water- and oil-proof, the current better alternative is film coating. PBAT is a wider application range and more composite materials used in the current pulp-molded environmentally-friendly tableware.

The coated product can better maintain heat preservation, reduce the heat dissipation through the pores of the molded product, and reduce the stickiness of food such as rice and dumplings, which can greatly reduce the use of water-repellent and oil-repellent agents.

Without any industrial decomposer, it takes about 45-90 days for the pulp molded environmentally friendly tableware to completely decompose in the natural state of the landfill. No harmful ingredients are produced, and it will not cause harm to terrestrial organisms, marine corals or marine organisms.

After degradation, 82% of the ingredients are organic matter, which can be used as fertilizer for land use, using natural materials and returning to nature.

The biodegradable pulp lunch box can be heated by microwave and baked in an oven without harmful chemicals in the product, and the temperature can reach 220°C.

Can support refrigerator freezing and refrigeration, freezing up to minus 18 ℃

The biodegradable plant fiber lunch box meets the national “Pulp Molded Tableware” quality inspection standards, the United States Food and Drug Administration (FDA), the German New Food and Diet Products Act (LFGB), and other standardized inspection standards.

Is biodegradable plastic tableware safe?

How to choose degradable plastic tableware? 1. Check the manufacturer's name, address, contact information, implementation standards, etc. (degradable plastics do not belong to the scope of licensed products, and there is no production license mark). 2. Check if the product is one-time use or repeated use. If single-use products are reused, some unknown risks may arise. 3. View the material. There are many types of degradable plastic materials, and some materials have special requirements. For example, PBAT materials must not be used to contact frozen foods and refrigerated foods, and PHB materials must not be used to contact ethanol-containing foods. - 4. Check the operating temperature (whether it can be used in microwave). Degradable plastics generally require a temperature of less than 100°C, and most of them cannot be heated by microwave. Some degradable plastics cannot be refrigerated or frozen (such as PBAT materials). 5. Check the type of food. Pay attention to whether there are special instructions not to contain certain special types of foods (such as acidic foods, alcohol-containing foods, oily foods, etc.). Picking tips Take a look: look at the color and impurity black spots, try to choose products with no impurity in the original color; Second smell: choose products with no peculiar smell and no peculiar smell; Three touches: Choose smooth-touch products, and try not to choose products with rough-touch feelings.

Increase the performance of plasticizers in disposable tableware.

In recent years, different types of whole starch biodegradable materials have been favored by researchers inside and outside the market. Full starch biodegradable materials usually refer to materials processed with a starch content of more than 80%. Plasticizers can also be degraded as a whole. Disposable corn starch tableware can be thoroughly decomposed by microorganisms, acids, alkalis, etc. existing in soil or water in a short time after being discarded. The products are carbon dioxide and water. An environmentally friendly material. Studies have reported that the addition of plasticizers can affect the mechanical properties of thermoplastic starch from different angles. On the one hand, it can increase the degree of plasticization of tableware, and on the other hand, it can promote the rearrangement of the chain structure and increase its hardness. In addition, the composition, size and conformation of starch molecular chains will also affect the preparation of thermoplastic starch. Studies have explored the effects of the crystalline structure and molecular weight of starch on the tensile strength, elongation at break and plasticity of the material. The relative crystallinity and crystal configuration of the starch on the surface will not affect its mechanical properties, but its straight The chain/branched chain ratio and molecular weight can obviously affect the relative performance of the prepared corn starch tableware. Other studies have also shown that the increase in the content of linear chains is beneficial to the improvement of material strength, hardness and solution viscosity, and the more likely to be shear thinning. Most disposable corn starch tableware uses glycerin as a plasticizer. However, due to the rearrangement of the starch molecular chain or inside, the thermoplastic starch material is prone to rearrangement and aggregation during storage, which causes the material to age and become brittle. Reduce or lose its application value. Researchers have done related studies in order to change the related defects. Among them, some people use urea, thiourea and guanidine hydrochloride and other amine-based compounds as plasticizers and found that such plasticizers can not only promote the occurrence of starch gelatinization behavior, but also restrict The deterioration of the performance of starch-based tableware. Some people also prepared nano-starch microcrystals by enzymatically hydrolyzing native starch, and then prepared disposable corn starch tableware by using nano-starch microcrystals under the action of glycerol. They found that strong hydrogen bonds can be formed inside the particles and between the particles and the particles. The interaction between the systems increases, resulting in an improvement in the overall performance of the cornstarch tableware. At the same time, the presence of smaller starch crystals can also slow down the aging degree of corn starch under high moisture conditions.

What material is used for degradable tableware.

The so-called degradable tableware is a new tableware product that can be decomposed into harmless substances under natural conditions through biochemical action. The original intention of the product design is to reduce pollution and protect the environment. Now the biodegradable tableware on the market can decompose into CO2. And water, its processing materials include natural materials and biodegradable plastics. Below we will explain in detail the two basic materials of biodegradable tableware. The first is natural materials, including pulp, straw, starch and other materials. Paper cups are used a lot. There is no need to introduce them here. Through the role of additives, starch (including corn, sweet potatoes, cassava, potatoes, etc.) and plant fiber (Mainly corn and other straw fibers) processed tableware is commonly called starch tableware. The additives used in this tableware are also degradable. Under the action of microorganisms, these items are first decomposed into glucose, and then converted into CO2 and water. In order to protect the environment, the shortcomings of this tableware are also obvious, that is, it is easy to mold, and the waterproof performance needs to be improved, because the raw materials contain a lot of food crops, and the production cost is also high. The second is degradable plastics. This product adds photosensitizers, starch and other materials to the plastic production process, so that most of them are degraded in the form of materials. As stated in the product structure, degradable plastic tableware does not have complete degradation. Ability, but the degradable components are decomposed under natural action, and the plastic part still exists, but it is broken down into fragments, this product should not be an environmentally friendly substitute. Through the above introduction, it can be found that there are still many problems with degradable tableware that need to be solved. We hope that in the continuous improvement of scientific researchers, we can use the above-mentioned degradable tableware products that are environmentally friendly, healthy, and economical.
