Introduction of Raw Materials for Pulp Molding Production

1. Bagasse pulp - the raw pulp molding material for the manufacturing production of molded pulp products

Bagasse pulp is a good raw material for molded pulp products. Bagasse fiber is mostly used in the production of pulp molded lunch boxes and tableware products.

Bagasse pulp is made of bagasse as raw material through chemical or biological pulping to make bagasse pulp. The bagasse pulp can be in a wet state, or it can be dried and pressed into a pulp board.

The bagasse pulp in the wet pulp state is then added with water to prepare a certain concentration of slurry directly for molded pulp manufacturing; while the pulp board is broken by a pulper and then water is added to configure a certain concentration of slurry for the pulp mold Plastic production.

A certain concentration of slurry is supplied to the pulp molding machine. The slurry is formed, shaped, and trimmed in a pulp molding machine to become a molded product.

Bagasse fiber is a medium-long fiber with the advantages of moderate strength and moderate toughness. It is currently the most suitable raw material for molded pulp products. Therefore, bagasse pulp products are currently the most widely applicable.

At present, bagasse fiber is mostly used in lunch box tableware products, and some high-end mobile phone holders and cosmetic packaging also use this raw material.

Bagasse pulp is produced all over the world, in Southeast Asia such as Thailand, in the Americas such as Colombia, Mexico, and Brazil, in the Middle East such as Iran, in China Guangxi, Yunnan and in other places.

There are a large number of sugarcane grown in these places. There are many sugarcane factories. Sugarcane is the raw material of sugarcane factories. Bagasse is originally the waste of cane sugar factories. However, many sugar factories have established bagasse pulp factories, which use bagasse to manufacture pulp and supply it to paper mills and pulp molding products factories.

With the development of pulp molding technology and the market, many bagasse pulp mills have begun to extend their industrial chain to pulp molded products. They purchase pulp molding equipment to build pulp molded products factories.

2. Bamboo pulp - the raw pulp molding material for the manufacturing production of molded pulp products

Bamboo pulp is a good raw material for molded pulp (plant fiber molding) products. Bamboo fiber is a medium-long fiber, and its performance is between softwood and hardwood.

Products made from bamboo pulp have strong toughness, cracks are not easy to appear when deep pulp molded products are produced, and the surface is smooth and delicate and has high whiteness.

However, fluffy fluff fibers are prone to appear after the surface of the product is rubbed. When the proportion of bamboo pulp exceeds 40%, it should be ground to eliminate the phenomenon of fluff fiber on the surface of the product.

Bamboo pulp is mostly used to make high-end mobile phone packaging inner supports, cosmetic packaging, and also used to make tableware. It is a good raw material for molded pulp products.

The production of products with complex shapes, small slopes and small R angles generally requires adding a certain proportion of bamboo pulp. Because bamboo pulp resources are more precious, the price is slightly higher than that of bagasse pulp.

Therefore, it is mostly used for blending with bagasse fiber in a certain proportion to increase the performance of molded pulp products while reducing costs. There are bamboo pulp production plants in northern China, Sichuan, and Jiangxi.
