Shangjun plastic products Co., Ltd. is a professional manufacturer of packing bag,such as side gusset bag and mushroom cultivation bags.How was the Side gusset bag produced? After the film rolls are produced from the machine, they are actually barrel shaped, We then roll the film through the machine and fold it out of the gusset. The same side gusset bag is produced by the film roll of different materials, and the role is very different, Our most famous side gusset bag is the PP mushroom Grow Bag.Now many buyers from European and American countries and some other countries will buy PP mushroom grow bags with filter patch from our factory to grow mushrooms.
◉ PP mushroom grow bags with filter patch The bag body is made of polypropylene, A filter patch was pressed 11 cm from the bag opening ,When the bag mouth is closed, it can also ensure that the medium can keep gas exchange with the outside of the bag and play a breathing role,At the same time, the aperture of the filter patch is only 0.2 or 0.5 micron, which can effectively prevent harmful bacteria from entering the bag and contaminate the original culture bacteria.
◉ Our PP film rolls are made with special raw material compensation mixture, which makes our PP mushroom grow bags with filter patch not melt and break when being sterilized at high temperature and high pressure.Also PP mushroom grow bags with filter patch Our same size bags can be selected from 4 options due to different thickness and filter patches.
◉ The thickness is 60um (2.2 mil) and 80um (3.1 mil) respectively,The aperture of filter patch is 0.2 and 0.5 micron, respectively.
