The benefits of black stretch film

stretch film production with simple operation, wide applicable range, good sealing, high transparency, low cost, high grade, etc. Suitable for medium and small batch products packaging. However, there is a kind of stretch film but also can have the benefits of recycling - — Black stretch film.

black with stretch film stretch film is general by extruder extrusion, has high tensile strength, puncture resistance ability and the resistance to impact have outstanding retraction memory and self-adhesive, by choosing different resin, can make the goods tightly wrapped into a whole, avoid pollution and damage during transport.

in addition, when the black stretch film after heating to the glass transition temperature, can guarantee the stable at room temperature. The hot shorter, heat and shorten the direction in the same direction, hot shortening rate can reach more than 70%. Heat shorten convenient polyester film is often used in food, beverage stores, electronic appliances, metal products, especially shorten the label is the main application fields. Due to the rapid developed, and the following bottles such as coke, Sprite, all kinds of fruit juice beverage bottle needs a set with stretch film do heat sealing label, come polyester class, environment friendly material, easy to recover the recycled use.

it can be said that the black stretch film is usually colorless stretch film has the following advantages:

first, valuables and privacy goods for packing, storage and transportation process can be well hidden packaging;

second, using the general recycling equipment, can reduce pollution of the environment, recycling black stretch film, saving the cost of packaging;

third, because of the pretensioning black stretch film thickness thinning, significantly fewer transportation when the total traffic volume, thus reducing the transportation energy consumption and vehicle emissions, directly or indirectly reduce the pollution to the atmospheric environment.

4, a direct result of the black stretch film pre-stretching technology processing, convenient use and high work efficiency. It can be said that under the weight of the same black stretch film for each roll length than normal wrap film more than double that of the length of per roll, packaging can reduce the frequency of the replacement roller.

but accordingly, comparing with the advantages of black stretch film, its production conditions are quite strict. Black stretch film melting point is 178 ℃, the maximum crystallization crystallization temperature is 141 ℃, and tensile process conditions is mainly related with the temperature, to produce high performance, high quality black stretch film will need to strictly control the production process conditions.
