Why can paper plastic composite bags be widely used in chemical, food, and condiments? This is inseparable from its manufacturing process and advantages. Today, Xiao Ou will promote the composite process of paper plastic composite bags.
The composite process of paper plastic composite bags can be roughly divided into four types: dry, wet and hot -melt type.
1. Coating method: This method refers to the method of coating on the surface of the membrane, which is closely connected to the membrane surface to the membrane. It can improve the thermal viscosity, humidity, gas isolation, ultraviolet absorption and anti -staticness of the membrane;
2. dry composite method: dry composite method, also known as dry layer compound legal, its process is to apply solvent -type adhesives on the basic thin film. The second layer of substrate heating and composite composite, the composite in the total amount is not only suitable for the composite between plastic film, but also for the composite between plastic film and aluminum foil and paper
3. Wet composite method: Wet composite method, also known as wet layer pressure composite. Its process process is: coated with water -soluble or water emulsion adhesive on the surface of the first layer of substrate. In a humid state, that is, squeeze and compose with the second -layer substrate through the composite device, and then remove it through the hot bakery to remove it. Solvent to compound two layers of substrates;
4. Hot melting composite method: This method is to dissolve the hot -melt adhesive to dissolve into a flow state, and then coat it, and immediately press the other thin film for composite. Compared with dry and wet composite, its advantage is that it does not require hot drying channels, uninterrupted compound time, energy conservation, low cost, and no solvents harm. Used for composite of paper, plastic and aluminum foil.
In order to allow everyone to use better, we are an industry expert and analyzed the details of the selection and correct precautions of paper plastic composite bags in detail:
1. Some colors of paper plastic composite bags are not very good in food packaging, because this paper plastic composite bag used to recover plastic in the past.
2. The weaving plastic composite bag from the library should be tasteless and tasteless, and there are some special composite bags, not forest paper packaging.
3. Buy it with more practical food and buy more money than street stalls.
4. Paper -plastic compound bags are not easy to degrade and easily cause environmental pollution. Therefore, composite bag wholesalers introduce food, very useful green packaging information.
Paper plastic composite bags must have Chinese signs, indicating that the factory name, factory address, and commodity operations cannot be marked with the words of food in these two parts. There are supply inspection certificates for goods transportation.
Try to choose products without coating. The current packaging scheme is equivalent to packaging, making it more beautiful, corrosion -resistant, and information. Not only do you remove a large amount of items after the recycling of substances, but you also remove the setbacks brought by reuse. Most of the coatings are poisonous. If we eat these packaging foods, they will cause a lot of physical and mental damage.
