What is a degradable lunch box

Mar 22, 2025

The country is now advocating environmental protection, and take-out businesses are gradually replacing ordinary disposable lunch boxes with biodegradable tableware to reduce take-out pollution. So what is a degradable lunch box? What are the main ingredients of the biodegradable disposable lunch box? The degradable disposable lunch box refers to the tableware that can be degraded into carbon dioxide and water. One of the material of the degradable lunch box is made of natural materials; the other is made of plastic as the main component, adding starch, photosensitizer and other substances. become. Next, I will introduce the relevant content of the degradable lunch box in detail.

1. What is a degradable lunch box?

Degradable lunch box refers to a lunch box that can undergo a biochemical reaction under the action of natural environment microorganisms (bacteria, molds, algae) enzymes, causing the appearance of mildew to the internal quality change, and finally the formation of carbon dioxide and water. The entire degradation process can be decomposed into harmless substances without human involvement, which is a very long process. In addition to the degradability of the degradable meal box product waste in accordance with GB18006.3-2020 "General Technical Requirements for Disposable Degradable Tableware", it should also have recycling value, be convenient for recycling, or be convenient for sanitary landfill and high-temperature composting. .

What are the main components of the biodegradable disposable lunch box?

Biodegradable lunch boxes use two kinds of materials: one is made of natural materials, such as paper products, straw, starch, etc., which are biodegradable and are also called environmentally friendly products; the other is made of plastic as the main component and added starch , Photosensitizer and other substances

Why is bagasse being used for the production of tableware?

Bagasse is the fibrous material that remains after the juices are removed from the sugarcane stalk. The fibrous portion generally becomes a waste product after the juices are separated. It is a widely used material for the production of tableware.

When it comes to the manufacturing of sugarcane bagasse biodegradable tableware products, it is remolded to a kind of paper that is used for making disposable cups, plates, and bowls. Lightweight, recyclability, and other unique attributes of the material make it the most preferred choice of packaging food products.

Our disposable tableware products are made from sugarcane bagasse. We has a wide variety of compostable and biodegradable products from disposable cups, plates, bowls to disposable boxes which are perfect for food services.

To check our amazing range of eco-friendly products.

Effects of plastic: Scientists find microplastics in human blood for the first time!

From the deepest oceans to the highest mountains, from the air, soil to the food chain, microplastic debris has appeared almost anywhere on the earth. Now, more studies have confirmed that microplastics have "invaded" human blood.

Usually, plastic fragments smaller than 5 mm in diameter are called "microplastics", and the extremely small size makes it difficult for us to notice their existence.

Scientists have detected microplastic pollution in human blood for the first time, according to a study published in the journal Environment International. Some previous studies have found microplastics in the gut, placentas of unborn babies, and in adult and infant feces, but never in blood samples.

The study examined blood samples from 22 anonymous healthy volunteers and found that 77% of the samples contained microplastics, with an average concentration of 1.6 micrograms per milliliter.

A total of 5 plastics were tested in the study: polymethyl methacrylate (PMMA), polypropylene (PP), polystyrene (PS), polyethylene (PE), and polyethylene terephthalate (PET).

PMMA, also known as acrylic or plexiglass, is mostly used for the appearance of electronic equipment and lighting equipment

PP is widely used in takeaway lunch boxes, fresh-keeping boxes, and some milk bottles

PS is widely used in disposable food packaging materials

PE is often used in packaging films and plastic bags, such as fresh-keeping bags, cling film

PET is usually used for the appearance of mineral water bottles, beverage bottles and various household appliances, etc.

The results showed that about half of the blood samples showed traces of PET plastic, more than a third contained PS, and about a quarter contained PE.

Even more shocking, the researchers found as many as three different types of microplastics in a single blood sample.

Studies have shown that these microplastics may enter the human body through various routes such as air, water or food, and may also enter the human body through specific toothpastes, lipsticks and tattoo inks. In theory, plastic particles could be transported through the bloodstream to various organs throughout the body.

The researchers say other kinds of microplastics may be present in the blood, but their study did not detect particles larger than the diameter of a sampling needle.

While the effects of microplastics on human health are unclear, researchers are concerned that microplastics can cause damage to human cells. Air pollution particles have previously been shown to enter the body and cause millions of premature deaths each year.

Lvwei degradable tableware has won praise in the market for its wide range of raw materials, easily degradable, recyclable and renewable distinctive features and environmental protection style, making it stand out among all kinds of plastic material substitutes, and the products can be in the natural state within 90 days It is fully degraded and can also be used for household and industrial composting. The main components after degradation are water and carbon dioxide, which will not produce garbage residue and pollution.

Can bagasse be used to produce moulded pulp tableware?

Bagasse can only be used to produce tableware after being processed into pulp by paper mills.

The structure of bagasse is complex, but its main components are cellulose, hemicellulose, and lignin. Among them, hemicellulose is about 20.6% and lignin is 18.6%. The content of cellulose in bagasse is about 35.4%, which is composed of β-1, 4-glycosidic bonds linked to glucopyranoside, which is a two-phase coexistence system (the coexistence of crystalline region and amorphous region). The crystalline region contains hydroxyl groups that easily form hydrogen bonds with surface water molecules, and the crystalline portion of cellulose is difficult to decompose. Hemicellulose is chemically similar to cellulose. It is a heterogeneous polysaccharide with different hexyl and pentose groups linked by β-1 4 oxygen bridges. The degree of polymerization is relatively small. It contains about 70% cellulose and 30% polyarabinose.

The main component of paper is plant fiber. Bagasse is rich in hemicellulose, cellulose, lignin, etc., which is an excellent raw material for papermaking. The energy consumption of pulp is too large and the cost of pulping is high, so try to eliminate lignin. Lignin is an important component of bagasse, with a molecular weight of 10,000-50,000 accounting for about 95%. The lignin in bagasse is mainly distributed in the epidermal tissue, and it combines with hemicellulose to form a firm protective layer, which hinders the contact of microorganisms or enzymes with cellulose, making it difficult to hydrolyze bagasse.

In papermaking, sugarcane pulp made from bagasse is usually produced on a large scale by chemical and mechanical methods, while pulp molded tableware usually uses the finished pulp board of the paper mill as a raw material, and cannot directly use bagasse.
