With the accelerated pace of society, more and more young people are eager to order take-out, even the culinary gods with excellent cooking skills will also have a little take-out experience. Such a development trend, so that the use of disposable tableware is also increasing. Eliminate “white pollution”, practice low-carbon behavior, the global popularity of “plastic ban”, so that every citizen of society more attention and choose to use environmentally friendly disposable tableware.
What are some of the environmentally friendly disposable tableware you are familiar with?
What is environmentally friendly disposable tableware?
Environmentally-friendly disposable tableware is a food container that is made of materials that are harmless to humans, non-toxic and tasteless, easily degradable, non-polluting in production, use, and destruction, and meet the national food hygiene requirements, and are easy to recycle and dispose of after use.
Common types of environmentally friendly disposable tableware
At present, when we talk about the topic of the most familiar environmentally friendly disposable tableware, many people may still say paper board tableware or kraft food container. Most of these paper lunch boxes are made of 300~350 grams of bleached sulfate wood pulp cardboard, made by die-cutting and pressing, shaping, and other processes. In order to prevent oil or water seepage, the surface should be laminated. It is non-toxic and has no side effects on the human body during the production and use process. However, the quality of the cardboard is high and the cost is also high, and the lamination layer is not easily degradable.
In addition to paper lunch boxes, environmentally friendly disposable tableware also includes wheat straw tableware, corn starch tableware, bagasse pulp molding tableware, etc. The compostable environmentally friendly disposable tableware produced by UV Tableware is made of bagasse pulp as the main raw material.
Does bagasse pulp molding tableware waterproof?
Sugarcane pulp tableware is made from bagasse after sugar extraction, replacing traditional petroleum-derived plastic or foam, and is currently recognized worldwide as 100% environmentally friendly tableware and 100% biodegradable tableware. Sugarcane pulp is also a kind of pulp, which is made from bagasse, the waste of sugar production, and is blended into a certain concentration of pulp through the process of hydraulic pulping and high-temperature sterilization, etc. This sugarcane pulp is a natural degradable and compostable plant fiber material!
Bagasse made into sugarcane pulp can save a lot of wood, but also in line with national circular economy requirements and environmental protection policies, so that the value of sugarcane to the fullest. The important parameters to measure the quality of bagasse pulp molding tableware are strength, water resistance, and oil resistance. Therefore, bagasse pulp molding tableware is definitely waterproof.
How do bagasse pulp food containers achieve the effect of water resistance?
One of the ways to ensure its water resistance is to add water repellents before forming and shaping the paper pulp tableware, adding water repellents must meet the non-toxic, non-corrosive, easy to disperse and other conditions, both to make tableware with water-resistant performance, but also to meet the health requirements of the use of pulp molding tableware, should also be considered to make pulp molding tableware after forming a good finish, and the cost should not be too high.

Pulp molded tableware waterproof agent selection and the choice of oil-proof agent has a close relationship, the current choice of oil-proof agent varieties less, and the traditional acid sizing system is not applicable, to make paper mold products have both oil-proof performance and waterproof performance, must take alkaline or neutral sizing system, the current more ideal neutral sizing waterproof agent is a synthetic rubber AKD (alkyl enol dimer for short). The process of action is AKD attached to —–AKD particles dispersed in the fiber surface ——AKD extension and a chemical reaction occur.
AKD and cellulose hydroxyl reaction is a slow process, unlike the acidic adhesive rosin attached to the fiber, its hydrophobic group immediately sizing effect. AKD sizing in the paper mold products after drying has not been completed. 24 hours sizing reaction is only completed 80%, and then a number of weeks are still in progress. If no adhesion measures are taken, about 35% of AKD fails due to hydrolysis. In order to improve the sizing effect of AKD glue and to ensure the oil and water resistance of paper mold tableware, effective retention measures must be taken.
How to verify the water resistance of sugarcane bagasse pulp molding tableware?
UV Tableware’s compostable bagasse tableware is tested in the lab after production. The water-resistance of bagasse pulp molded tableware can also be tested in a very easy way by the end consumer or distributor, as seen in the video below.
