Inventory of popular disposable degradable tableware on the market

In the environment of promoting environmental protection, more and more businesses have gradually replaced ordinary disposable lunch boxes with degradable tableware to reduce environmental pollution. many.

So what is a degradable lunch box? What are the main ingredients of degradable lunch boxes? What is the difference between degradable lunch boxes of different materials?

Degradable tableware refers to tableware that can undergo biochemical reactions under the action of microorganisms (bacteria, molds, algae) and enzymes in the natural environment, causing mildew in appearance to change in internal quality, and finally forms carbon dioxide and water.

There are two kinds of materials used for degradable tableware: one is made of natural materials, such as paper products, straws, starch, etc., which can be fully degraded, also known as environmentally friendly products; the other is plastic as the main component, adding starch, photosensitizer and other substances, can be partially degraded.

Today let's take an inventory of the disposable degradable tableware on the market.

Cornstarch-based cutlery

Cornstarch-based tableware is a relatively common degradable lunch box on the market. The main source of starch is corn, so it is sometimes called cornstarch-based, but this type of lunch box is actually a mixed plastic of starch and traditional petroleum-based PP, which is called abroad. Bio-based.

Cornstarch-based tableware is the breakdown of the physical properties of the entire material through the biodegradation of starch, but the petroleum-based PP after the collapse is still non-degradable. Lunch box, and can not be regarded as fully degradable.

Therefore, cornstarch-based tableware can only replace plastic products to a certain extent, and it is a substitute for the controversial plastic tableware on the market.

Pulp molded tableware (plant fiber molded tableware)

In terms of raw materials, the pulp-molded disposable lunch box uses plant fibers such as wheat straw and bagasse as raw materials without adding any PP materials. , to achieve the effect of serving hot and cold food.

Plant fiber-degradable lunch boxes are also one of the most active types of lunch boxes on the market. Take Hainan Province, which took the lead in banning plastics, as an example. Hainan Province has completely banned the use, circulation, sale, and storage of plastic tableware. Pulp-molded tableware is undoubtedly to be the ideal plastic replacement.

Sugarcane pulp disposable lunch box is a fully degradable type of lunch box, which can be completely degraded into organic matter in 90 days under industrial composting or household composting conditions, returning to nature. It is a fully degradable material in the true sense and has Certainly superior.

PLA degradable tableware

PLA degradable lunch boxes usually refer to products that combine PLA composite film with pulp molding products in the pulp molding process, that is, PLA film products.

PLA composite film is produced and processed from polylactic acid as raw material. It can be composited on pulp molding and paper products by heating. It is a completely degradable film.

Polylactic acid (PLA) is a new type of biodegradable material made from starch raw materials proposed by renewable plant resources. The starch raw material is saccharified to obtain glucose and then fermented from glucose and certain strains to produce high-purity lactic acid, and then the chemical synthesis method is used to synthesize polylactic acid with a certain molecular weight.

After the lamination process is combined with the pulp molded product, the use of waterproof and oil repellant can be saved, and it can play the role of sealing the pores of the pulp molded product. Holds longer.

However, the degradation of PLA needs to meet the following conditions:

1. A large number of microorganisms;

2. When the temperature exceeds 30°C, microorganisms will begin to degrade PLA;

3. Humid, the higher the humidity, the higher the hydrolysis efficiency.

It can be said that the environment that meets these conditions at the same time is very rare in nature.

At present, many pioneering countries in the world to ban plastics in the world, such as Europe, do not use degradation and complete degradation to describe materials, but whether they are compostable or not. Because compostable can limit the degradation time, particle size after degradation, and the influence of degraded components on plant growth to ensure the safety of materials.

Therefore, such as pulp molded tableware and plant fiber molded tableware (sugarcane pulp tableware), truly environmentally friendly tableware that can be completely degraded under home composting conditions is now showing a hot development trend in the market.

The GREENOLIVE production site is in accordance with industrial hygiene and safety standards and meets the requirements of BRC, ISO9001, and ISO 14001 standards for the production of food packaging.

GREENOLIVE holds the industry's compostable certification - the most widely used compostable standard in Europe EN13432 and US ASTM D6400.

At present, GREENOLIVE's biodegradable tableware product line is launched with sugarcane pulp, straw pulp, PLA, PBAT, etc. as raw materials, including but not limited to disposable fully degradable dishes, cups, trays, packaging boxes, coffee cups, cup lids, etc., as well as some medical packaging and other products, all procedures are processed in the dust-free workshop to ensure that the environmental protection standards are met.

According to different application requirements, we provide one-stop product customization, which can meet the systematic customization of catering packaging.
