PVC shrink sleeves produce marvellous looking packs, perfect for soap making supplies, bath bombs, oil bottles, CD cases, giftware, candles, cosmetics, wine bottles, shoes, books and much more but they have been largely superceded by Polyolefin (POF) shrink films. Whilst PVC shrink sleeves have particularly easy sealing and shrinking features, they are inferior to POF shrink films in the areas of strength, low temperature flexibility and their associated cleaning regime on equipment.
However, PVC shrink sleeves continue to fulfil certain areas, such as on very flexible packs, particularly heat sensitive products and, or where older shrink wrap equipment is in use, where their particular benefits can come to the fore.
PVC shrink sleeves is also used with less plasticiser in the form of semi-rigid shrink film where it can be used to substitute BOPP overwrap film, but with the additional benefit of a shrink wrap finish.
