Elevation offers an automatic Slider Zipper Bag Sealer or sometimes referred to as Pactiv Zipper Bag Sealer. This Continuous Band Sealer is specifically manufactured to address the challenges of bag sealing equipment for Slider Zipper bags or Pactiv Zipper Bags.

The Sealer is setup in such a way that it will weld the opposing side of Slider Zipper Bags or Pactiv Zipper Bags.

Band Sealers can seal wide range of heat sealable films. Although used primarily for soft films (polyethylene), also known as unsupported films, they can be used on certain hard films (supported or high-density films such as polypropylene) and specialty films.

Band sealer speeds are considerably faster than intermittent types of sealing and perform well on various bag styles including gusseted. Syntegon Technology is launching its new, redesigned continuous band sealer machine range. The Doboy CBS-D and B-550 not only have new names – CBS-D 1500 and CBS-D 750, respectively – but feature improved operability in combination with the proven technology of their predecessors.

Woven polypropylene bags have been used as an alternative to burlap or paper bags for many years and have been typically closed with sewing machines. Sewn bag tops contain holes which are an avenue for infestation and moisture to enter the bag contents.

Syntegon recognizes that this has long been an industry problem. Building on over 70 years of industry experience, Syntegon now offers three machines designed to seal woven polypropylene bags:

• Double fold and glue
• Double fold and tape
• Conventional heat seal.

Glue Sealers are intended to seal paper bags. We offer two fold styles: A double loop fold and a triple or square top fold. These two fold styles provide a secure closure and prevent product sifting. The double fold produces a strong sift-proof closure that is popular for a wide variety of consumer products.

Glue Sealers offer high speed closing and are typically incorporated into a fully automatic bag liner. Speeds up to 100 bags per minute are obtainable.

Pinch Style Sealers close multiwall paper bags with product weights from 20-100 lbs. A pinch style bag features a stepped end to expose the plies of a multiwall bag. Hot melt is pre-applies by the bag manufacturer. The final closure involves reactivation of the hot melt and folding the stepped end over to bond with the face of the bag.

Pinch style bags may also feature a separate inner liner that is heat sealed in addition to the pinch closure. This results in a hermetically sealed bag and is commonly used in toxic products that are hydroscopic.
