Poly Bag Manufacturing Process

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.

Plastic Strapping Buckles

Image
Plastic and Wire Buckles The work volume, production speed required, and required strength deter­mines closure method. For low volume, low tension applications, buckles are a good method of joining plastic strapping. This is particularly true if portability and cost are major issues. One can easily hand tension the strap, with or without the use of a hand pull or crank tensioner, and apply the buckle without the need of a power source. The metal buckles are stronger than the plastic ones and can withstand greater tensioning. Plastic buck­les are used on lighter weight loads, espe­cially in agriculture, as they can be easily hand applied in the field without the need for tools. Always Use: Phosphate finished buckles on bonded and all woven cord strapping. Galvanized finished buckles are required for composite cord strapping Bright finished buckles are for polypropylene strapping.   Read more on the other types of plastic strap closures and check out our selection of buckles

Poly sheeting for construction applications

Image
The construction industry uses poly sheeting. Poly sheeting for the construction industry   provides a temporary support of existing structures and the soil their on. The polyethylene material stands up to the elements and pressures during construction. Their biggest advantages to working in the construction industry is that they're water-proof, rot-proof, and resistant to chemicals. Poly sheeting can be used for construction, landscaping, masonry and more. Poly sheets are highly durable, have high strength, and are tear resistant. Plastic sheeting is useful for industrial applications, protection against the elements on construction sites, moisture and gas barriers and many other innovative uses. Poly sheeting for construction benefits: Construction enclosures Erosion control Shipping and packaging Insulation membranes We offer many poly sheeting packaging supplies in different mil thicknesses: 1 mil ,  1.5 mil ,  2 mil ,  3 mil ,  4 mil ,  6 mil ,  8 mil ,  10 mil

Coffee Pods - a Sustainable Solution or Fleeting Fad?

Image
  Whether you use them or not, single-use coffee pods have taken the world by storm... and with quite a large amount of controversy. So what made a luxury coffee producer choose aluminum for their coffee pods?   Luxury coffee producer Nespresso chose to use aluminum to create their pre-portioned capsules because it offered the best protection from oxidation, preserved coffee freshness, and prevented food waste through leftovers. (According to the Sustainability Manager at Nespresso, the kitchen sink is the largest source of consumption of coffee made by standard drip pots.) Now, we know individual coffee pods can be controversial, even to the point of attempted ban in the US and Europe, and creating aluminum is no easy process either. So why did Nespresso choose Aluminum where Keurig chose plastic?   In 2009, Nespresso decided to source sustainable aluminum with the help of the International Union for Conservation of Nature. By 2015, Nespresso has 14 non-government organizations
