Plastic Strap Metal Seals

Polypropylene Smooth Metal Seals

The proper steel seals for polypropylene straps are smooth metal seals. A tensioner and the correct sealer with symmetrical jaws will produce tight professional seals.

 

Polyester Serrated Metal Seals

The proper metal seals for polyester straps are serrated metal seals. Look at the open seal in the picture below. If you look closely, you can see the rough texture fabri­cated inside the seal for better gripping power on slick sur­faced polyester. A tensioner and the correct sealer with non—symmetrical jaws will produce tight professional seals. Be sure to place the long tooth of the sealer over the long open top of the seal (see arrows) before crimping.

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

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
