Plant fiber pulp products and disposable degradable pulp molded products have been favored by the market in recent years. One of the reasons is that it has significant advantages over alternatives in terms of environmental protection, price, and performance. The second is the strong support of the government and the influence of the global environment. Today, we analyze the advantages and disadvantages of plant fiber pulp product classification and disposable biodegradable pulp molding products.

1. Ordinary pulp products

As the name implies, it refers to the molded products made of yellow pulp, newspaper pulp, A4 pulp, etc. of carton boxes, which have low hygiene requirements and low prices.

2. Sugarcane pulp products

Sugarcane pulp products refer to molded products that are made of wet pulp or pulp board after being pulped by biological pulping. Sugarcane fibers are medium and long fibers with the advantages of moderate strength and moderate toughness. Said to be the most suitable raw material for molded products, so sugarcane pulp products are currently the most widely used.

3. Wheat straw pulp products

Wheat straw pulp products are divided into mechanical fiber wheat straw pulp molded products, chemical-mechanical wheat straw pulp molded products and chemical wheat straw pulp molded products. Wheat straw pulp has short fibers, good stiffness, brittle products, and poor flexibility. Neutralization of long fibers is required to increase the toughness of its products.

4. Bamboo pulp products

Bamboo fiber is a medium and long fiber, and its performance is between softwood and hardwood. The products produced by bamboo pulp have strong toughness and smooth and delicate surface, but fluffy fibers are prone to appear, with complex logarithmic shape, slope and Products with a smaller R angle can be added.

5. Wood pulp products

Wood pulp products are mainly divided into softwood pulp and hardwood pulp. Softwood pulp has long and fine fibers, and the wood pulp is relatively pure and has few impurities.

Hardwood pulp fiber is thick and short, and contains more impurities, the strength of the finished product is relatively low, the finished product is relatively loose, the absorption performance is strong, and the opacity is high. Paper made from softwood pulp has good flexibility, high folding resistance and good tensile strength. Paper made from hardwood pulp has high bulk, high stiffness and good packaging performance. Therefore, the thickness and density of products produced by different wood pulp will be different.

6. Reed pulp products

Reed pulp products are mainly used in papermaking, and are mostly used in low-grade products in molded products. Reed pulp is not easy to remove reed knots in the production process, has many impurities, and has low whiteness, but it is cheap and has good drainage. It is fluffy, so the finished product with the same gram weight is thicker and takes up more space.

7. Palm pulp products

Products made from fibers extracted from palm fruit and palm leaves are rarely used, mainly because the oil content of palm is high, which is not easy to remove, but has good stiffness.

8.Melon and rattan pulp products

Melon and vine pulp is a general term. All kinds of melon plants such as yellow vine and loofah vine can be used to produce molded products. However, different types of fibers are also very different. Most of these fibers are short fibers with relatively high stiffness. Poor, and impurities are not easy to deal with, so it is not widely used.

9.Cotton stalk pulp products

Cotton stalk pulp products only use cotton stalks. After removing the surface layer, the cotton stalk intermediate tissue is used to produce and process products. Cotton stalk fiber molding products have relatively fluffy fibers and poor stiffness, and are mostly used in low-grade papermaking.

10. Machine-milled fiber products

The method of refining is used to disperse the plant fiber raw materials into fibers under the action of mechanical force. The pulp produced by this method is called mechanical pulp. The machine-molded fiber is not separated from lignin and cellulose, and the fiber binding force is poor. It needs to be used in combination with chemical-mechanical pulp or chemical pulp. The amount of machine-molded fiber added should not exceed 50%, and the products after more than 50% are more prone to chipping.

11. Chemical pulp products

Chemical mechanical pulp refers to a certain chemical treatment before refining, and the obtained pulp is called chemical mechanical pulp. Chemical mechanical pulp generally contains higher lignin and cellulose components and lower hemicellulose components. , the pulp yield is higher. This type of pulp is mostly used in mid-range molded products, and its cost is higher than that of mechanical pulp, but lower than that of chemical pulp, and its bleaching, hydration and drainage performance is relatively close to that of mechanical pulp.

12. Chemical pulp products

It is mainly a molded product processed by acid and alkali pulping after chemical treatment. This kind of product is fine and smooth, and the pulp retains more lignin content in the raw material.

With the strengthening of people's awareness of environmental protection and the favor of the market, the classification of plant fiber pulp products and disposable degradable pulp molding products will usher in greater development.
