Printashrink PF-A1 4-1

Printashrink PF/A1 4-1 is a 4:1 shrink ratio, dual wall heatshrink polyolefin with an integral thermoplastic adhesive liner. It provides encapsulation of inner components, environmental sealing and moisture-resistant insulation, and is available in black and clear as standard in sizes up to 52mm ID. It can be cut and printed as required.

This glue lined, 110°C, 4:1 general purpose tube consists of a flame retarded heatshrink polyolefin tube with a thermally activated inner adhesive liner. The inner liner melts and flows to encapsulate connectors and components providing a moisture-resistant, environmentally protective, permanent seal which is able to accommodate greater differentials between pre and post shrinking. It is available in 1.2 metre lengths or on reels, and can be supplied with UL approval. We offer a range of printing and cutting services on this high strength, resilient tube also making it perfect for identification, branding and marking requirements.

Free Artwork Service

As part of the fully comprehensive print process, we offer a free artwork service for both thermal and hot foil printing. This involves, advising on print suitability, resizing to fit final fitted size and re-ordering information supplied in spreadsheet format according to the sequence of installation or into kits.

To ensure superior print results, it stands to reason that artwork needs to be best quality and this is why we advise on whether artwork is suitable for purpose in terms of fine detail and ornate graphics which may not successfully transfer to smaller sleeves and markers, or where a high shrink rate is required. Furthermore, as heatshrinkable products do not shrink in a uniform manner (transverse and longitudinal shrink ratios differ widely) we resize artwork so that there is a strict correlation between original and final fitted dimensions.

We accept many formats for artwork including, but not limited to, tiff, eps, bmp, jpg, gif and PDF. For jpeg, save your image using the best quality. We use a single colour print system. This means the sleeving and print can be different colours, but the print itself can only be one colour. For best results send your image in black and white with what you would like printed in black. We can then take the image and print it on your selected sleeving in the correct print colour.

We also print from spreadsheets, CSV or text files, .lists or drawings. Where required, we can sort, print and pack according to the sequence of installation.
