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 a...

BONDED POLY CORD STRAPPING (non-woven) Bonded cord strapping is used as a safe, inexpensive product for bundling and securing a wide variety of items across a multitude of industries. From agriculture, landscaping, automotive, printing, light building products, to baling corrugated and plastic for recycling, bonded cord strapping is your best solution.   WOVEN CORD STRAPPING Woven cord strapping provides additional bi-directional strength and split resistance often required in harsher environments. General purpose woven cord strapping is cost effective and ideal for securing and bundling light to medium/ heavy loads for most industries. Heavy duty and extra heavy duty cord strapping are super tough-high tensile products designed for application to replace more expensive steel strapping. These products are used primarily for securing heavy and extra heavy loads in the bundling, metal and plastics industries as well as for rail car load securement.   COMPOSITE CORD STRAPP...

Containment Force Force to load is the amount of force the film exerts on the load to maintain its integrity. This is extremely important when down-gauging. This measurement will show you that the load integrity is just as good, or better than it was before.                     Keys to Containment A wrapping standard is established Total film revolutions are consistent Containment force is equal Film weight is known, consistent, and repeatable   Pre Stretch: Normally a fixed value affected by the equipment's gear ratio. This is the amount of stretch achieved in the equipment's pre-stretch rollers. Force-to-Load Stretch: The amount film stretches as it is applied to the load. This figure may deviate from the equipment's pre-stretch. Factors such as equipment settings and film composition affect the "on pallet" stretch. Cut and Weigh:   Exactly what it says. Cut the film off and weigh it. This is the...

Ultimate An ultimate break is a straight-line break with pointed edges. The break occurs when the film has been pre-stretched beyond its limits.         Film Flaws Bad Edges Film has nicks or flaws in edges Causes a tear from on edge through the film Creates a diagonal break May also be caused by machine rubbing edges Gels Unmelted Plastic in film Causes a tear from on the center of the roll Creates a diagonal break from gel point May also be caused by burrs or nicks on rollers Why do failures occur? No understanding of containment No wrapping standards established No adherence to a developed standard   Make sure you know the difference between cast and blown stretch film and check out our selection of stretch wrap .

What is AAR and AAR approved strapping? AAR stands for the Association of American Railroads, an organization that independently test strapping for rail car packaging. The Packaging Group sells several types of Polyester strapping with different characteristics. Search our collection of AAR approved plastic straps by finding the (AAR) listed under "Type". How do you remove plastic straps? Since plastic straps are applied under tension and retain their tension, it must be removed with caution. Eye protection is required even though plastic strapping may not be perceived to be as sharp as steel strap­ping, it still can cause serious cuts or even blindness. As pictured to the right, wearing safety glasses, place a hand on one side of the plastic strapping to be cut. With solid footing, also place your body in front of your hand holding down the strap and away from the free side of the strapping. When the strapping is cut, the free side will fall away from you. On th...

How to Load a Coil Onto a Dispenser Most plastic strapping is shipped with protective and securing packaging. The coil pictured below has a protective shrink wrap­ping. Many of the narrow­er straps also have corru­gated side plates to avoid problems like massive unwinding and pull downs (see photos). Using a pair of scissors or safety knife carefully cut the plastic stretch film out of the core opening. Keep all of the remaining packaging on the coil until the coil is tightened securely on the dispenser, then, and only then is the top pack­aging cut carefully off the top edges of the coil with a safety knife or scissors. Always leave the side plates on and don't worry about the shrink wrap remaining on the sides of the coil. Your plastic strap is ready for use now that it's been properly loaded onto the dispenser!   Be sure to check out our full selection of plastic straps, tools, and accessories .
