Basic Applications of Nylon Plastic Strap
In addition to an understanding of the character of a package or load, selection of strapping and equipment requires an understanding of basic applications. There are nine basic plastic strap applications, and they are as follows:
1. Unitizing- Unitizing is the bringing together of a number of relatively small product items into a single, larger unit. Most often, this is done for handling purposes. It is similar to palletizing and skidding, but unitizing generally does not require a rigid base.
A unit- load is usually uniform in shape: square or rectangular, hexagonal etc. The items in the load might include hundreds of bricks, or sections of pipe, but the overall shape will be uniform.
Other unitizing materials may be used with the strapping. A unit-load of asphalt drainage pipe, for example, may be held together by wooden “rings” of two-by-fours. The two-by-fours are “encircled” and held together by the strapping. This provides a rectangular, stackable load and allows lift truck handling.
2. Bundling- Bundling is similar to unitizing for the strapping gathers together a number of small items into a package or load that is easier to handle. Bundling is a smaller version of unitizing. The bringing together of several bundles would be described as unitizing.
3. Palletizing- Palletizing is the securing of a load of packages on a pallet. Most often, the packages are corrugated cartons. But they can be shipping sacks, drums, pails, tote boxes, or virtually any industrial package that can be assembled on a pallet.
But the items need not be packages, many individual items or assemblies, uniform in shape or made uniform by supporting damage, can be assembled on a pallet and secured by strapping. Or, large single items can be fastened to a pallet.
4. Skidding- Skidding is a heavy-duty form of palletizing. A skid generally has two runners made of heavy timber, but no bottom deck. Products loaded on sides are usually heavy: paper, slit coils, cut-to-length steel, large aluminum coils, and tin plate.
5. Closure- Closure with nylon plastic strapping is most commonly done on containers which you plan to use more than once. It is done with corrugated cases, plastic returnable containers and covered tote boxes, and certain one-way shipper. The nylon plastic strapping is easy to apply and easy to remove without damaging the container.
6. Securement- Securement is usually defined as making sure that a product will remain in a given configuration: large coils that might unwind, slit coils, transformer cores, and rod packs.
7. Reinforcement-Reinforcement means increasing the structural integrity, or strength of a container. It takes many forms. A container with heavy, loose contents- like a corrugated case full of washers- is less likely to burst its sides under shock when strapped around its girth.
Some large appliance packages are handled by a lift truck attachment that slips under the top flap. The flap is reinforced with nylon plastic strapping.
8. Baling- Baling is a method of holding loose compressible material together. Baling reduces cube and makes a uniform, load that is easy to handle and store. Materials commonly baled include cotton, and synthetic fibers, and scrap paper, metal and corrugated.
The materials are compressed in a baling press while nylon plastic straps are fastened around the circumference.
9. Car loading- Car loading refers to the securement of loads in or on rail cars. Typical products secured in rail cars are: lumber, paper rolls, telephone poles, large pipe, machinery, and other heavy equipment. It was once done exclusively with heavy-duty flat steel strapping, but can now be done with heavy-duty nylon plastic strapping.
Glossary of Terms
· Abrasion Resistance: Ability to resist breaking along rough or sharp edges.
· Break Strength: Amount of tension (pounds) required to break (tensile strength).
· Camber: Amount of wave; degree of straightness.
· Creep Resistance: Stability under load; ability to maintain tension.
· Elastic Memory: Ability to recover original state.
· Elongation: Amount of stretch.
· Embossing: The texture given to facilitate ease in handling and reduce splitting
· Moisture Resistance: Degree to which moisture is retained or repelled.
· P.S.I.: Pounds per square inch- a measurement of material strength. Break strength of one-inch square of a given material.
· Shock Reserve: Amount of “give” in a strap; ability to hold rather than break under sudden stress.
· Split Resistance: Degree of orientation in a strap. A monoaxially oriented strap will split relatively easily.
· Temperature Resistance: Ability to remain stable despite high or low temperatures. Higher temperatures can increase the “creep” in non-metallic strapping.
· Joint Efficiency: Breaking strength of the strapping joint is a percentage of the breaking strength of the strapping.
