Description

Co-extrusion antirust aluminum foil film

Technical Field

The utility model belongs to the field of packaging, and particularly relates to a co-extrusion antirust aluminum foil film.

Background

Stainless steel, silicon steel, aluminum plate and other metal products and some nonmetallic electronic devices are easy to be influenced by other environmental factors such as water vapor and oxygen in the transportation and circulation processes, so that the metal and the electronic devices are easy to rust and damage products, and therefore, the metal and the electronic devices are required to be protected and packaged in the storage and transportation processes. In terms of the conditions required by the packaging material, the packaging material is required to have rust-proof and moisture-proof functions at first because the articles are often stored for a long time and are often wet and rusted due to the change of climate and temperature and humidity in the transportation process, and in addition, the packaging material is required to have certain strength so as to completely seal and pack large-sized articles such as machines and ordnance articles, thereby effectively playing the rust-proof and moisture-proof effects.

The existing antirust film is prepared by compounding an HDPE plastic film and an antirust agent, the HDPE plastic film has certain waterproof property and electrical insulation property, but has poor ageing resistance and mechanical property, is easy to deform and age, has low surface hardness, is easy to crack and break under the condition of high stress or temperature, and the antirust factor can exert the maximum effect only in a closed space, so that the protection requirement cannot be met, and needs to be improved.

Disclosure of Invention

The utility model aims to solve the problems of insufficient protective capability, poor mechanical property and easiness in breakage and cracking of the traditional antirust film.

In order to achieve the above object, the present utility model provides a co-extrusion antirust aluminum foil film.

According to the utility model, the co-extrusion antirust aluminum foil film comprises an antirust layer, a barrier layer and a base layer which are sequentially arranged from inside to outside, wherein the base layer is an aluminum foil film, the barrier layer comprises at least two barrier layers, and the antirust layer and the barrier layer are composite layers formed based on a co-extrusion molding process.

Alternatively, the rust-proof layer is a rust-proof master batch-polyethylene film.

Alternatively, the barrier layer comprises an inner barrier layer and an outer barrier layer, the inner barrier layer comprises a PET film and/or a PA film, and the outer barrier layer is a nylon film.

The utility model has the beneficial effects that: by adopting the polyethylene film as the antirust layer material, the waterproof and dampproof effects are achieved; the barrier layer adopts PET, PA films and nylon films, and the PET and PA films have excellent mechanical properties, wear resistance, toughness and good air tightness; the nylon film has higher tensile strength and tensile strength, excellent puncture resistance and better heat and cold resistance and oxygen resistance; the aluminum foil film has good mechanical property, strong light shielding property, high heat and light reflecting capability, low possibility of being corroded, good barrier property, moisture resistance and water resistance, and the barrier property of the film is greatly enhanced by adopting the aluminum foil film as an external insulating layer; the rust-proof layer is used as a packaging inner layer, and rust-proof factors can be better released in a closed space wrapped by the barrier layer and the insulating layer, so that the rust-proof effect is maximized; and compared with other composite processes, the adopted multilayer coextrusion technology can save about 30% of production cost, reduce the use of chemical adhesives and is more environment-friendly.

In conclusion, the co-extrusion antirust aluminum foil film disclosed by the utility model has the advantages of good antirust effect, low production cost, excellent barrier property, excellent waterproof, dampproof, shading, oxygen-insulating, heat-resistant and cold-resistant properties, excellent mechanical properties, wear resistance, high tensile strength, difficult breakage in packaging large-scale machinery, capability of effectively protecting products to be packaged, strong air tightness and maximized antirust effect.
