Turn waste into treasure, using bagasse as raw pulp to make disposable tableware.

Mar 30, 2025

With the strengthening of the country's "plastic ban", the first industry affected by the "plastic ban" is undoubtedly the catering industry. Various traditional plastic straws and plastic lunch boxes will gradually withdraw from the market, and will be replaced by more environmentally friendly degradable straws and tableware. "Pulp moulding" tableware has therefore become the "new darling" of the market. The reason why the "new darling" here is quoted is that this type of product did not come into being because of the "plastic ban". In fact, such products in foreign markets have long been It is very popular, mainly in the European and American markets, especially in the European market. Due to the environmental awareness of Europeans inscribed in their bones, such products are loved by the public in Europe.

What is Pulp Molding?

Pulp molding tableware refers to pulp tableware made of pulp through molding, molding, drying and other processes. It can be divided into molded paper cups, molded paper bowls, molded paper lunch boxes, mold Plastic paper plate, molded paper plate, etc., the color is generally white and natural.

Features of Pulp Molding

The product uses virgin fiber pulp as raw material, and its raw materials come from a wide range, mainly wood pulp, bamboo pulp, straw pulp, sugarcane pulp and so on. Due to the wide source of raw materials and strong renewability such as bamboo pulp, straw pulp, sugarcane pulp, etc., the price is cheap and easily accepted by the market. In terms of strength, it is superior to other similar products, and has a large recycling value and is degradable. It is regarded as a green product. Unfortunately, in the past, these products were almost sold to Europe and the United States as export products, while foam and plastic lunch boxes were almost used in China. The long-term irreversible damage to the environment caused by the cheap price is not worth the gain.

Why are there mostly sugarcane pulp plates on the market?

First of all, let's take a look at sugarcane. The following content comes from Baidu Encyclopedia. "Sugarcane is mainly distributed between 33° north latitude and 30° south latitude, of which the area is relatively concentrated between 25° north and south latitude. Sugarcane is native to India and is now widely used. Planted in tropical and subtropical regions. The country with the largest sugarcane planting area is Brazil, followed by India and China in third place”

"About 50% of the fiber in the bagasse left after sugar extraction can be used for papermaking. However, some of the pith (pit cells) do not have interlacing force and should be removed before the pulping process. Bagasse Fiber Length It is about 0.65-2.17mm, and the width is 21-28μm. Although its fiber shape is not comparable to wood and bamboo, it is slightly better than rice and wheat straw fibers."

To sum up, it is a sentence, sugarcane is more and fiber texture is good, more suitable for making pulp molded dinner plate.

Which takeaway box is the healthiest? A must-see for takeaway packaging!

Most of the utensils for takeaway food on the market today are made of plastic. Careful people will find that there are numbers on the plastic boxes seen in daily life. What do these numbers represent? They represent different materials of plastic and are generally represented by the numbers 01 to 07.

No.1 polyethylene terephthalate (PET)

It is often used to make mineral water bottles, carbonated beverage bottles, etc. This material is heat-resistant to 70 °C.

No.2 High Density Polyethylene (HDPE)

It is often used to make plastic containers for cleaning supplies, bath products, etc., which can withstand high temperatures of 110 degrees Celsius, and plastic bags marked for food can be used to contain food.

No.3 polyvinyl chloride (PVC)

It is often used in the production of building materials and belongs to toxic plastic products. "Toxic" mainly refers to the single-molecule vinyl chloride that has not been fully polymerized in the production process, as well as the harmful substances in plasticizers. These two substances are easy to precipitate when encountering high temperature.

No.4 Low Density Polyethylene (LDPE)

It is often used to make cling film, plastic film, etc., and the heat resistance is not strong. When the temperature exceeds 110 °C, a hot melt phenomenon will occur, leaving some plastic preparations that cannot be decomposed by the human body. Therefore, when the food is wrapped with this plastic wrap for heating, the oil in the food can easily dissolve the harmful substances in the plastic wrap.

No.5 Polypropylene (PP)

It is often used to make special lunch boxes for microwave ovens. It can withstand 130 ℃. It is the only plastic box that can be put into microwave ovens. It can be reused after cleaning.

No.6 Polystyrene (PS)

It is often used to make bowls of instant noodle boxes and fast food boxes, which are heat-resistant and cold-resistant. But it cannot be put into a microwave oven to avoid the release of chemicals due to high temperature, and it cannot be used to hold strong acids and alkalis.

No.7 Other plastics (PC)

Contains bisphenol A, which is harmful to health.

The plastics from 01 to 07 are introduced above. The content looks a bit professional, but after understanding their respective uses, you will understand that only 02, 05, and 06 are high-density polyethylene (HDPE), polypropylene (PP) , Polystyrene (PS) is relatively safe to make lunch boxes.

Are paper boxes safe?

One is the coated paper lunch box, that is, there is a thin layer of polyethylene plastic coating on the carton, which is equivalent to a layer of plastic film covering the paper surface. This kind of paper lunch box can withstand high temperatures of about 90 ° C, suitable for hot and cold drinks, and can play a good role in water insulation. The cost is higher than that of plastic lunch boxes, and the cost price is mostly less than 1 yuan.

The other is aluminum foil lunch box, the quality is better than the coated paper lunch box, its raw material is non-toxic, easy to heat, and does not produce harmful substances after heating; high temperature resistance, up to 660 ℃; easy to seal, strong barrier, sealing It can protect the original taste of food and prolong the shelf life of food; it can be recycled and reused efficiently. Aluminum foil lunch boxes are now popularized in aviation, high-speed rail and primary and secondary schools. However, due to the higher cost, takeaway catering businesses are less used.
