According to the requirements of the packaged products and the characteristics of the structural design of the paper support factory products, the relevant parameters in the design are determined.

① Size and wall thickness. Paper holder paper-plastic packaging products is to ensure that the basic requirements of the structural design and by close contact between the packing materials, prevent the packing materials produced in the process of circulation list, on the basis of the cushion and shock to consider, so the paper packaging structure design must be compact in size, compact size is fixed bearing surface and the cavity and the strengthening of comprehensive reinforcement cooperate to solve.

The wall thickness of paper support should be determined according to the use conditions and the types of paper fibers used in the packaging structure design of paper support factory. The wall thickness is an important factor affecting the strength of paper support. The increase of wall thickness not only increases the consumption of raw materials, but also reduces the production during adsorption molding. The increase of wall thickness also increases the energy consumption of wet paper mold drying process, and easily makes the paper support produce quality defects such as depression, shrinkage hole and sandwich. The wall thickness should be reduced as far as possible under the premise of satisfying the strength of paper support. The wall thickness of vacuum adsorption molding process is between 0.5–6mm, and the wall thickness of pressing molding process is between 3–20mm.

Packaging of paper support factory

② Demoulding inclination. In the packaging molding process of the paper support factory, the wet paper mold is close to the net mold and the paper fiber will be embedded in the mesh of the net mold. In order to facilitate the transfer of the wet paper mold, the paper support surface parallel to the direction of demoulding should have a reasonable demoulding slope. The greater the inclination is, the more convenient the demoulding is. If the inclination is too small, the demoulding is difficult, and the paper support surface will be pulled or broken. Too large inclination will reduce the size accuracy of the paper holder, but also affect the bearing capacity and elastic recovery force of the paper holder. General demoulding slope take 3°- 6°.

③ Transition arc. In the design of paper support structure, the corners of the inner and outer surface of the paper support package, the connection between the vertical bar and the main body and the terminal of the vertical bar must be transited with circular arc to avoid straight edges and right angles. The TRANSITION OF PACKAGING ARC IN PAPER SUPPORT PLANT IS BENEFICIAL TO MOLD manufacturing AND mesh attachment, to DEMOLD WHEN wet paper mold is TRANSFERRED, TO FLOW OF pulp support material during adsorption molding, and to avoid packaging damage caused by stress concentration. The radius of the transition arc can be determined according to the specific product and the performance of the paper and the special requirements of the packaging, generally 2- 5mm.

Pulp support packaging raw materials —- sugarcane pulp introduction

Sugarcane pulp and corrugated pulp are the most commonly used packaging materials in the paper support packaging industry. Sugarcane pulp is a kind of pulp support, which is made of sugar mill waste bagasse as raw material and prepared into a certain concentration of pulp through hydraulic pulp crushing and high-temperature disinfection. Domestic paper packaging manufacturers will generally use imported sugarcane pulp, in the form of sugarcane pulp board.

Sugarcane pulp pulp tray packaging

The beaten sugarcane pulp is absorbed into a wet blank product (paper support packaging embryo body) by vacuum on a special metal mold. The formed wet blank is then dried and hot-pressed into the paper support packaging style we want.

Sugarcane pulp is a by-product of sugar factory, and its supply is highly concentrated. Sugarcane pulp can save a lot of wood in the packaging industry of paper support factory, which is in line with the economic requirements of recycling and environmental protection policy of China, and waste recycling.

Sugarcane pulp pulp packaging products are widely used in electronics, electrical appliances, communication equipment, computer accessories, glass, ceramics, lighting, arts and crafts, cosmetics, health products, wine, fruits, eggs and so on.
