Welcome to Printasleeve - High Quality Printed Sleeving Products for All Your Professional Needs

Printashrink CPF/FR4

Printashrink CPF/FR4 is a 4:1 shrink ratio heatshrink polyolefin with a working temperature of 135°C. It is a fire retardant sleeve perfect for difficult or irregular shapes where an unusually high shrink ratio is required. Supplied in black as standard, diameters up to 115mm ID are available and can be cut and printed as required.

This 4:1 heatshrink polyolefin tube is designed for commercial or industrial applications where an extremely high ratio is needed to cover irregularly shaped pieces or pass over large components before shrinking. It has excellent electrical, chemical and physical properties and we offer a range of printing and cutting services on this high quality, commercial sleeve making it equally suitable 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.
