Acrylic is the medium priced pressure sensitive tape and features excellent clarity and resistance to yellowing. It may be applied in temperatures ranging from 32-140 degrees, is a great general purpose tape and is the favorite when carton appearance is an important consideration. Natural Rubber Packaging Supplies Company''s natural rubber tape has a strong PVC backing which is very quiet coming off the roll and accepts magic marker on the surface of the tape without smearing. Natural rubber adhesive is the best pressure sensitive tape for sealing cartons in extreme temperatures (0-150 degrees), humidity or dampness because it quickly forms a long lasting bond. Natural rubber tape is darker than acrylic or hot melt tape and yellows as it ages. Natural rubber is the most expensive pressure sensitive tape available. Polyester is the most rigid of all strapping materials. shipping inventory it elongates significantly less than polypropylene and retains tension over a longer period. polyester is nick resistant and can be sealed with seals, heat or friction inventory welds. because polyester offers the greatest strength and highest retained tension of all plastic strapping, it is frequently used on heavy duty loads that need high initial tension along with high retained tension during handling and storage. common applications shipping are empty cans and bottles, lumber and heavy, rigid palletizing. polyester has a smooth, inventory shiny finish and is easy to dispose of and recycle.polypropylene strapping is the most commonly used and least expensive of all strapping materials. it is light and easy to apply and recycle. characteristics include high elongation and elongation recovery, but low retained tension. polypropylene is an excellent choice for light duty palletizing, unitizing, carton closing and bundling. because of its embossing (or waffle) pattern, strap thickness is not a useful measurement. shipping a standard 1/2" machine grade strap can be embossed to a thickness of anywhere between .014 and .030, depending upon how deep inventory the embossing pattern is. an overly embossed strap will be thicker, but will have a lower break strength. carton reinforcement: a 3:1 ratio of strap to carton weight is recommended. for a 100 lb package this could be done with (1) 300lb tensile strap or (2) 150lb straps. unitizing and bundling: a 5:1 ration shipping of strap to carton weight is recommended. palletized cases: required tensile strength = (pallet weight x 1.5) / # of straps with these definitions in mind, you may review the comparison chart below and see which product or combination of products makes sense for your specific applications. product comparison chart boxes inventory standard boxes in hundreds of sizes variable depth boxes give you several box sizes in one carton cube boxes are very popular becuase of the broad application - great for shipping almost any item. long, tall and flat box sizes are also available for more specialized sizing needs. corrugated mailing supplies lightweight, yet strong enough to handle a wide variety of product packaging applications. literature mailing supplies are shipping great for manuals, books, binders and computer printouts media mailing supplies are specially designed to safely ship cassettes, cd''s and videos indestructo mailing supplies are crushproof yet lightweight inventory cartons that assemble without staples, tape or glue.
