A label is provided for a bottle in the form of a heat shrinkable sleeve made of oriented polyethylene. The label is made as a laminate having inner and outer layers. The outer layer has a coefficient of friction of less than about 0.15. The inner layer has a coefficient of friction of greater than about 0.4. The inner layer includes ethylene vinyl acetate. The layers are about 0.001 inches. The layers are connected by an adhesive, which is about 0.00005 inches thick. A plurality of sleeves can be formed from a planar strip wherein first halves of the sleeves are formed adjacent each other along half of the strip and complementary halves of the sleeves are formed adjacent each other along the other half of the strip, whereafter the strip is folded in half to bring the first halves into alignment with the complementary halves and the thusly constituted portions of the sleeves are heat sealed or welded together.
A covering for a container comprising inner and outer layers, and means connecting said layers in laminate form, said outer layer having a greater degree of slip than said inner layer.
An article of manufacture comprising a bottle and a stretched sleeve encircling and compressively engaging said bottle, said sleeve having inner and outer portions, said outer portion including a fatty acid and having a greater degree of slip than said inner portion.
A method of making a covering for a bottle comprising fabricating a sleeve of heat shrinkable material and forming the sleeve with a greater degree of slip in the outer portion of the sleeve than in the inner portion thereof and with a greater circumference than the bottle and heat shrinking the sleeve onto the bottle.
