DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet for forming a shrinkable sleeve, and an object of the present invention is to provide a material suitable for a shrinkable sleeve for protecting glass bottles containing carbonated beverages and the like.

Conventionally, the outer surface of a glass bottle, etc. is covered with a sleeve made of a heat-shrinkable synthetic resin sheet, and when heated, the sleeve is shrunk to cover the outer surface of the glass bottle, etc., and the glass bottle, etc. is transported. Buffer protection is provided during storage.

However, the various synthetic resin sheets conventionally used as materials for sleeves have been unsatisfactory, as they are inferior in either their cushioning protection properties or their properties in preventing scattering of bottle fragments. For example, non-foamed sheets such as polyvinyl chloride sheets and stretched polystyrene sheets are effective in preventing bottle fragments from scattering;
Bottles have poor cushioning and protection against shock and vibration during transportation (9%).Although foam sheets such as expanded polystyrene sheets have excellent cushioning properties, they have poor elongation and tensile strength, so they are less effective in preventing bottle fragments from flying off. It wasn't on point.

That is, foamed seams) (1) alone has the drawback that, although it has poor cushioning properties, it causes fragments to scatter when the dust breaks, resulting in poor safety. Therefore, by making the entire non-foamed film (2) an i-layer, the non-foamed film (2), which has good stretchability, remains uncut even after cutting the foamed sheet (1) when storing bottles. After absorbing the flying force of the bottle fragments due to the elongation of (2), the non-foamed film (2) will be cut Ifr.

In addition, since the non-foamed film (2) allows the shrink sleeve (4) to stretch as a whole, even if the bottle is damaged due to a drop or an impact load, the sleeve (4) stretches and deforms to the bottle itself. It also has an excellent protective performance that reduces the load on the bottle and prevents damage to the bottle.
