Widely used by users of special-shaped bags

Volpak has developed a brand new chewing gum bag that resembles the packaging of homemade cigarettes produced by the American Tobacco Company. The top of the bag has a sealed zipper and cigarette paper.

At the same time, in response to the demand of some customers for packaging bags to help increase brand recognition, Mespack, a Spanish packaging machinery manufacturer, has also produced special packaging machines that can produce shaped bags and are used by several large-scale manufacturers. Adopted by multinational corporations.

Representatives of the UK's special-shaped bag machinery manufacturers are Clan Packaging Machinery. The company's design and manufacture of equipment can produce 12 different shapes of three-side sealing, four-side sealing and stand-up pouches. The difference between the various bags is mainly reflected in the shape, sealing zipper, cover design.

In general, relatively large bags and stand-up bags are produced using horizontal equipment, because horizontal machines can be relatively flexible to change the form of the bag. Smaller, metered bags are produced by vertical machines. These bags can be mass produced at the same time, but the disadvantage is that the machines are less flexible in adjusting the package appearance. However, at the 2004 Total Packaging Exhibition, we saw a new vertical form-fill-seal integrated packaging equipment VVI developed by Rovema, which can produce three-side sealing, four-side sealing, and self-supporting bags. VVI combines the advantages of traditional horizontal and vertical bag packaging machines: It uses a completely closed system and is suitable for aseptic packaging and vacuum packaging. Another feature of VVI is that it can produce various types of bags with a speed of 600/minute.
