A heat-shrinkable sleeve starts out with a thick extruded polyolefin sheet (polyethylene or Polypropylene) that is formulated to be cross-linkable. After extruding the thick sheet, it is taken to the "beam" where it is passed under a unit that subjects the sheet to electron irradiation. The irradiation process cross-links the polyolefin. This improves the molecular structure such that the polyolefin will work as part of a heat-shrinkable sleeve and provide the required level of mechanical protection while in-service. It makes the polyolefin perform more like a tough, heat-resistant, elastic material, than like a plastic material.
After cross-linking, the sheet is stretched by feeding it into a machine that heats it up, stretches it and cools it down. Because the sheet has been cross-linked, after stretching, it will want to recover to its original length when re-heated

What products used shrink sleeve applications.?
Shrink sleeve applications, in which the label is wrapped around the product and then shrunk directly on to it to form a bond, were most common on batteries and film products.
Difference between Pressure Sensitive label and Shrink Sleeve label?
Pressure sensitive labels (ps labels) are adhesive backed labels that can be applied by hand or using automatic labeling equipment using slight, even pressure. The advantages are ease of application, versatility and permanence on a product. Shrink sleeve labels are non-pressure sensitive and are applied to a product then 'shrunk on' with heat and/or steam. Getting the graphics right for shrink sleeve labels can be tricky as a precise distortion factor must be factored in to preserve the integrity of the graphics. When using either label type be sure to work with an experienced and reputable label printer. Label Impressions, Inc. (www.labelimpressions.com) is a highly recommended source for labels in California and the West Coast.
What are the use's of a heat shrink wrap?
The main uses for a heat shrink wrap is the wrapping and storage of equipment including boats, bridges and food packaging. There are endless uses for heat shrink wrap.
What is better heat shrink or sleeve for computer wires?
If it is the cabling within your system tower (or more commonly CPU), then I would suggest using sleeves since internal computer cabling usually needs rewiring with almost every change in the hardware or fault conditions. A heat shrink would severely limit this. At the same time, the air gun you would use to shrink could even damage the components near the cables if done improperly.
What is an heat shrink tunnel?
Heat shrink tunnels are used in shrink wrapping products. They are used to quickly shrink wrap all sides of a product at once, which is more efficient than using a heat gun and only shrinking one side at a time.
Which company invented the heat shrink tubing and when?
Heat shrink tubing was invented in the 1950s, in the later years, by Raychem Corporation. The head engineer founder was Paul Cook who used radiation chemistry to invent heat shrink tubing.
what, is a heat shrink tunnel.?
No you don't need one if you're always cold. A heat shrink tunnel is a machine thats very often on a conveyor belt that assist in the packaging on boxes with shrink wrap, its job is to apply heat so the shrink wrap is snug up against the boxes.
What services does Heat Shrink provide?
The website Heat Shrink offers heat shrink tubing. The company cuts to specifications as well as offering the service to print logos onto the tubing. The website itself seems fairly straightforward to navigate.
Does high heat shrink clothes?
Yes, high heat can shrink clothes because it can cause the fibers in the fabric to contract and become tighter.
How do you make your clothes shrink?
To intentionally shrink clothes, wash them in hot water and then dry them on high heat. This can cause the fabric to shrink due to the combination of heat and agitation. Be aware that this method may cause damage to some types of fabrics.
Where can one find information on heat shrink tubing?
Heat shrink tubing provides a state of the art method for the application of a tights, protective covering to items that will be subjected to the extrems of heat, corrsion.
Why does cold air shrink balls?
