White/plain or coloured with labelling field . close-it is an aluminium-backed, vapour-proof adhesive label with extremely strong adhesion. Sacks, boxes etc. which have been pierced with samplers can be hermetically resealed. They can even adhere to slightly moist or dusty sacks coated with fine powders, e.g. plaster, flour etc. Close-it food & pharma ensures aswell the necessary success when resealing sample openings, as it reliably prevents products from escaping after sampling. The adhesive complies with the European guidelines for foodstuffs. Just like the original, close-it food & pharma has a barrier layer of aluminium foil, which makes the close-it food & pharma perfectly suited to sampling foodstuffs, pharmaceuticals, cosmetics, food additives - any applications in which the product must not be contaminated by contact with the adhesive.
