Mailing Tubes Great for shipping or storing maps, blueprints or other documents that are best kept unfolded. We offer kraft tubes, white tubes, snap seal tubes and square tubes. Boxes Box dimensions are inside dimensions and stated packingbubble in the (L x W x H) sequence. Length (L) is the larger of the two dimensions. (L x W) is the measurement for the open top of the box. Width (W) is the smaller dimensions of the open top. The height (H) or depth is the dimension that measures the inside height or depth of the box. Packaging Supplies Company''s stocks RSC type containers. RSC (Regular Slotted Containers) means that all flaps are the same lengths in the height (H) direction and the length (L) side flaps meet in the center of the box when folded in the closed position. JPadded The standard padded mailer - rugged and durable. Available in self seal and regular styles. Bubble For maximum cushioning around your package and outstanding printability. Available in self seal and regular styles Foam packingbubble For clean, dust free surface protection with packingbubble light cushioning . Available in self seal style. Rigi Bag Extra rigid for superior corner and edge protection. Shurtuff A great low-cost alternative to Tyvek envelopes. Easy to print on, water resistant, accepts gummed labels and is completely opaque. Stayflats The industry standard for rigid mailing supplies. When rigidity is critical to your application, then Stayflats are an excellent, economical choice. Available in tab seal and self seal styles. Literature Mailing supplies When an envelope mailer cannot do the job, check our line of literature packingbubble mailing supplies. Great for manuals, book and printouts too. Polyester is the most rigid of all strapping materials. 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 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 are empty cans and bottles, lumber and heavy, rigid palletizing. Polyester has a smooth, 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. A standard 1/2" machine grade strap can be embossed to a thickness of anywhere between .014 and .030, depending upon how deep 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 of strap to carton weight is recommended. Palletized Cases: Required Tensile Strength = (Pallet Weight x 1.5) / # of Straps
