である。又包装等の用途のみでなく本材料は大証の空気
を包含している材料であるから断熱材、浮材としての利
用も考えられるがその場合にも粘着剤が塗布してあれば
使用が簡便となる。And if this material is coated with adhesive,
For example, it can be used more effectively as a packaging material.For example, it can be attached to a desired part of a product and can conveniently provide partial cushioning. When packaging products, strings, etc. are not required. If the surface of a plate-like object is maintained a''c, the purpose can be achieved with the minimum amount of material required.In addition to being used for packaging, this material is also suitable for insulation as it contains OSE's air. It is also possible to use it as wood or floating material, but in that case, it will be easier to use if it is coated with an adhesive.
しかし乍ら本材料に粘着剤を＃２！存する事は、本材料
の厚さが２ｍｍ及至５ｍｍとＨいため、その巻いたもの
は短尺で大径となり粘着剤塗布の際非常に非働率的であ
る。However, adhesive #2 is added to this material! However, since the thickness of this material is 2 mm to 5 mm, the rolled material is short and has a large diameter, making it extremely inefficient when applying adhesive.
又空気泡を軟質ポリエチレン薄膜中に包含しているため
、材料は非常に軟弱で通常の粘着剤塗布工程では良好な
塗４ｊは困難であるＣ）発明が解決しようとする問題点
未発ＩＩＩは空気泡を包含するポリエチレン令シートに
粘着剤が塗布された材料を製造するにちり、上記問題点
を解決した製造方法を提供するものである。In addition, since air bubbles are included in the soft polyethylene thin film, the material is very soft and it is difficult to achieve good coating using a normal pressure-sensitive adhesive coating process.C) Problems to be solved by the invention III: The present invention provides a manufacturing method that solves the above-mentioned problems in manufacturing a material in which a pressure-sensitive adhesive is applied to a polyethylene sheet containing air bubbles.
Ｄ）問題を解決するための手段 いまその問題点を解決する手段を図面により説明する。D) means to solve the problem Now, means for solving this problem will be explained with reference to the drawings.
