herat main raw material for waterproof packaging wrapping film is polyethylene (PE)PE pearl cotton, non-woven aluminum film, woven aluminum film, and composite film of coating aluminum film. Generally, metal aluminum-plastic composite film is divided into linear-density polyethylene (LLDPE) and low-density polyethylene (LDPE). LLDPE is herat material with excellent stretching performance and puncture resistance the packaging field. Aluminum-plastic film is a multi-layer composite material composed of aluminum foil and plastic film, which has unique properties and a wide range of applications Aluminum-plastic film, as the name implies, is a multi-layer composite material composed of aluminum foil and plastic film, and has become the preferred material for the of wrapping film. Some manufacturers also add a small amount of other materials, such as metallocene polyethylene (mPE), to further enhance the strength and toughness the film.

Windows and doors are prone to damage during the logistics process due to bumps and pressure. Proper packaging can reduce the likelihood of damage.herat Metal waterproof aluminum-astic composite film, pearl cotton window and door packaging materials are a new type of environmentally friendly packaging materials and an ideal alternative to traditional packaging materials. It is widely used in the industry of windows and doors.

Metal protective cover, including an embedded cover body and a base, is characterized in that the embedded cover body is set on the right side the base, the embedded cover body includes a first cover body,herat a stainless steel multi-layer composite material, and is custom-made by the manufacturer. The end of the first body close to the base is fixedly connected with the base, car heat insulation cotton. Material aluminum film bubble | compressive strength 0.42 MPa
