MANUFACTURING DESIGNS
BOTTOM SEAL: These bags are cut individually from seamless tubing and are sealed at the bottom of both flat and gusset bags. This is the strongest seal available and is suggested for bags with heavy-duty uses.
SIDE SEAL (SIDE WELD): These bags are made from folded polyethylene sheeting, sealed on each side. This seal (or weld) can be used on at and gusset bags and is suggested for retail uses.
BAGS ON PERFORATED ROLLS: These bags are made on a continuous roll of seamless tubing perforated at specified intervals for ease in tearing the bag off the roll. The “top” opening can be above or below the perforation. This storage configuration takes minimum storage space and is routinely used for bin liners, pallet covers and very long bags. Pre-opened bags are suitable for automated bag-filling machines.
BACK SEAL: For these bags, polyethylene sheeting is folded and sealed along the backside of the bag to form a tube. The bags are cut and bottom-sealed and are the required type of bag for wrap-around printing.
HEADER PACK: These are side welded bags with a perforated top lip stapled to a header card. They are used with semi-automatic bag opening machinery or in manual operations. They are packed with 100 bags per header card.
FLAT SHEETING: Sheeting is used for wrapping, lining and dividing layer.
WICKET BAG: These are side-welded bags with two holes in the lip fi> to a metal wicket. They are used with automatic and semi-automatic I openers or in manual operations.
RECLOSABLE BAGS: Seal Top reclosable bags can be made with or without
a tamper evident seal. The use of these bags is preferred when there is the need for multiple entries or repackaging of the bag.
HEADER BAGS: These bags are side-welded with a continuous sea along the top width, 2"-3" below the fold. The bags are loaded and sealed from the bottom. Reinforced headers are available.
FLIP-TOP BAG: These are side-welded bags with a fold over lip.
POCKET BAG: These bags are sealed in separate pockets along their length for the purpose of multiple unit packaging within a single bag
DOOR KNOB BAG: These are side-welded, staple packed bags with a perforated lip and hole just below the top of the bag.
