1. The paper tray industry is about to become a huge processing and manufacturing industry. The paper tray packaging and printing industry has provided good development opportunities in the "Eleventh Five-Year" development plan.
2. The level of paper tray printing technology continues to improve, and at the same time, the level of paper tray packaging technology requirements have been improved.
3. The application range of paper tray packaging is becoming wider and wider. It has established a firm foothold in many industry markets and needs continuous development. For example, the market share of wine, food, cosmetics, small household appliances, electrical meters, etc. is increasing. .
4. The level of paper tray packaging is improving with the improvement of corporate customers. In order to meet the value of their own products, enterprises put forward higher requirements on the outer packaging of paper trays.
Design considerations
1. The advantage of pulp wood plastic molding is that it has less impact on the environment, so it is often selected as an ideal material for environmentally friendly products
2. Untreated pulp generally has two kinds of brown and gray. Brown pulp is generally processed from kraft paper. Gray pulp is synthesized from recyclable printing paper. In contrast, brown pulp has better strength and recoverability.
3. Pulp molded products are in the form of thin shells
4. The product dried in the air is smooth on one side (the side that is attached to the mold), and the other side is rough, so product details are generally added on the smooth side (the side that is attached to the mold), such as logos and explanatory texts, etc.
5. The wet pressing method can improve the surface quality of the finished product; while the hot pressing method improves the surface quality, it will reduce the permeability of the product
