Benefits of using polyethylene in packaging. Double seam vs Euroseam

ServisPromPak and ServisPromPak Group are the modern manufacturers of packaging materials to order. Deliveries go all over Belarus and Russia: to large food-processing plants , to small and medium-sized enterprises.

The company’s products are tested, safe and at reasonable prices. The reason is the optimization of all costs and processes, as well as the use of advanced new technologies. For example, packages 0.100x600x1200 mm and 0.080x600x1200 mm have a wide euro-seam and are able to withstand significant loads. They replace from 2 to 3 analogues of LDPE 0.060x600x1200 mm, which reduces the cost of goods.

Benefits of using polyethylene in packaging

Many manufacturers of packaging materials have appreciated the positive properties of polyethylene a long time ago:

  • simple processing,
  • convenient storage,
  • lack of consequences when exposed to precipitation,
  • small weight,
  • high strength,
  • elasticity.

Another advantage is the reliability of the connection. Parts of the material are heated until melting begins, and then strongly compressed. Cohesive forces occurs at the molecular level, therefore it is highly reliable.

IMPORTANT: The strength of the seam is affected by two factors: the quality of the raw material and the thickness of the material!

The following are the features and differences of the seams.

DOUBLE SEAM

In the manufacture of flat poly bags, W-Cut handle bags and other packaging, two parallel seams are often used. To obtain a seam 1-2 mm thick, devices with two parallel heating elements are used.

It is a mistake to assume that if one fastening line is broken, then the product inside the package will be held by the second seam. Practice has shown, that polyethylene is torn at the place of solder failure.

Euroseam: advantages and features of manufacturing

To create a euroseam (it is also called a wide seam), special equipment is used. The specification of the device is that it heats the material from both sides. This allows you to get an even and extremely strong connection with a width of 5 to 10 mm.

Polyethylene of white, black and any other color is suitable for soldering. The dimensions of the future packaging also do not matter. We produce bags with logo of various shapes (W-Cut handle bag, D-Cut handle bag, U-Cut handle bag), flat poly bag and stretch film (including for food use). You can buy packaging material wholesale and retail, the current price must be specified in advance.
