Release time：2021-01-13
About the quality of pulp fiber molding, raw materials are the first element, more common is divided into two categories;One is the original pulp such as: wood pulp, bamboo pulp, sugar cane pulp, straw pulp, etc., this kind of pulp or pulp paperboard without impurities, is the original ecological plant fiber, can be used to produce meal boxes and tableware and other food contact packaging supplies.The second kind is recycled paper such as: corrugated paper, book paper and newspaper, gray board white board paper.This kind of paper generally produces industrial packaging electronics and other packaging products.
Good quality pulp fiber molded products must first be flexible, but also have a certain hardness, and have a certain moisture-proof function. It is not easy to return to moisture and become soft in a humid climate.The appearance should be clean and smooth, but also can add some color customers like to mix.
There will be many problems in actual production, such as: 1. Poor quality of molded pulp fiber products?2 what kind of paper to make the product cost low, and so on a series of questions.
Here are some lessons learned to improve the quality of pulp fiber molded products:
1, mold design, structural design is the key.The basic principle of shock resistance and cushioning of pulp molded products is realized through the spatial structure and the position of stiffeners.Therefore, different design structures of the same pulp will have different shock resistance strength and different effects.
2, pulp fiber is different, pulp molding the same type of mold will use different pulp due to pulp fiber length and shrinkage characteristics are different, feel will be different, in the selection of raw materials, we should know the need to achieve seismic standards, to choose different pulp.
3, the pulp fiber molding product production process and production equipment is crucial to the quality of the product, generally according to the shape of the product, product quantity to determine the process and machine model, these factors determine the efficiency and production of each link of the production details, directly affect the product quality and profit margin.
