Bag types: 1: Press the bag type and function: self-reliance in food packaging bags for food packaging bags vacuum bags of all kinds of self-nozzle beverage bag sample pictures (20) self-reliance in food bag shaped bag in box wine bags of high-temperature cooking liquid food tea bag foil coffee bags anti-static shielding bags and electronic products UV bag of supplies linked to the movement of portable self-paste bone zipper bag document bag milk soy milk bag: coating process according to the raw materials and equipment used in different customized kraft paper bags can be divided into that process and pre-coated film-coated film processes. And these two processes are mainly: solvent-free hot melt adhesive laminating film dry laminating process and the wet emulsion adhesive that is coated composite technology. Solvent-free hot melt adhesive laminating film composite woven dry compound, complex production processes have been simplified to a single hot concentrated together, is currently the widely adopted. The wet emulsion adhesive coated composite technology that is the core technology mainly for coated paper composite cement bags custom, cold, dry three areas. The difference between them is the type that is coated directly after the coating nip End precoating type adhesive di After application of the adhesive is dried and then hot-pressed. Kraft kraft color editing source of raw materials for different reasons, different production batches, different production seasons, different production machines machines, and so many reasons will affect the kraft paper roll is not the same color, the color is not the same as it is difficult to avoid but not control, generally the same batch of 98% kraft paper can ensure consistent color. [3] surface using refined white kraft paper or kraft Hebei yellow composite woven manufacturers, which uses plastic woven by high temperature and pressure to melt the plastic particles PP, the kraft paper and plastic composite woven together to plus endometrial bag. Paper bag bottom opening form equivalent to sew pockets having good strength superior characteristics, such as coated paper is waterproof plastic particles by casting machine coated paper surface of the composite material, the main feature is the composite material can be prevented oil, water (relative), you can heat.
