The bubble film produced by the bubble film bag making machine is a new type of plastic packaging material with light texture,good transparency,non-toxic and tasteless.It can prevent moisture,buffer and heat preservation for products.Bubble film is a product that takes high-pressure and low-pressure polyethylene as the main raw material,adds whitening agent,opening agent and other auxiliary materials,and then extruders and blisters into bubbles at about 230℃.It is a new type of plastic packaging material with light texture,good transparency,non-toxic and tasteless.It can prevent moisture,buffer and heat preservation for products.
The mixing energy of bubble film bag making machine is partially transformed into the surface free energy of concrete.As a result of air entrainment,the free energy of rod concrete system increases,and air entrained concrete becomes a thermodynamic unstable system.
As the middle layer of the air cushion film is full of air,it is light,transparent,elastic,and has the performance of sound insulation,shockproof and anti-wear.It is widely used in anti-seismic cushioning packaging for electronics,instruments,ceramics,handicrafts,household appliances,bicycles,kitchens,furniture,paint products,glass products and precision instrumnets.It can be made into bubble bag,bubble kraft paper envelope bag,automobile sun shield,heat insulation material,etc.
By adding different additives to plastic raw materials,various special air cushion films such as anti-static can be made.Anti static air cushion film is used for packaging electronic components,components,such as boards,cards,etc.,which can not only prevent static electricity,but also play a buffer and anti vibration role.
