There are big difference and discrepancy existed between China’s egg tray machine and that from oversea countries. In terms of egg tray packaging units, there aren’t too much difference. In terms of molding units, rotary molding solution are used for both China and oversea countries. Chinese egg tray machine had also been exported outwards with […]
Pulp molding products, such as egg tray or egg box, are widely used in oversea counties. Take U.S. for instance, almost all the pulp molding products come from waste paper. The yearly consumption of waste paper is 45000 tons, with annually increasing rate of 40%. The total consumption reached 810000 tons up to 2000. In […]
Normally, the products coming out of the egg box machine is loosed and soft in texture, it’s necessary to condense the egg box into a solid consistency, or density. One of the solution is to use condense machine, the semi-fiinshed egg box is placed between two molds, when the molds are closed, the extra moist […]
Virgin paper and other recycled materials can be used directly for the egg tray machine. The composition of wasted paper is very complex, some in straw-based printing material, such in wood-based waste newspaper, some in grass pulp mixed waste cartons. Egg tray produced by the different components have different properties, therefore, to obtain better economic […]
Paper pulp packaging industry adopts paper pulp, virgin pulp or waste paper, as raw material, by shaping through molds with filtration mesh, the water will be hydrated by negative air pressure, the remaining fiber will form the final package shape. Now the typical Chinese paper pulp industry follows below procedures: Hydra pulping – pulp pools […]
At the beginning of 1900s, the paper making had become a world-wide industry instead of family-size mill, various types of paper and paper pulp products had enter all aspects of people’s daily life. The industry is very prosperous in France, U.S., Japan, Canada, Iceland, U.K., Denmark, Singapore and Netherland with large scale production. The development […]
In recent year, there are three major ways in the world to deal with the pollution that caused by wasted packaging stuffs: 1, avoid packaging, 2, recycle the packaging, 3, using decomposable material to the the packaging dissolved natrually without making any damage to the environment (also called 3R1D protocol). In some countries like U.S., […]
The main equipment for egg tray pulp molding production includes hydraulic pulper, pulp pools, shaper, dryer and hot presser and edge cutter. The shaper is the most critical part of the production, there are several kinds of shapers for the pulp molding, one is called rotating pressing shaper, mainly used in apple trays, egg trays, […]
