[China Packaging Network News] pulp molded products are mainly used in industrial packaging, such as poultry trays, fresh fruit trays, food and semi-finished product packaging, medical equipment packaging. Pulp molded products are generally processed using multiple sets of molds. With the improvement of mold technology, cavity-shaped pulp molded products have been produced at present, and most of these pulp molded products are used as containers or decorations. The combined processing form is a packaging function required by a plurality of differently shaped pulp molded bodies to achieve a certain application during molding. In foreign countries, disposable pulp-molded urinals have replaced the repeated use of urethanes made from polyester materials. With the improvement of mold technology, the structure of pulp molded products has become more and more complicated and refined.
In addition to the traditional honeycomb paperboard, corrugated paperboard and pulp model products, foamed paper particles that are currently meeting environmental requirements are gradually being developed and applied in the buffering of electronic products. A company in Hamburg, Germany, shreds used paper and mixes it with starch. The slurry is made into granules, placed in a sealed container, subjected to high pressure and high temperature steam, and then rapidly depressurized. The pellets are foamed. The formation of porous beads made of foam packaging material, can be used as a buffer material, buffering performance than EPS, suitable for electronic, instrument and sensitive material buffer packaging.
