【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、精密機械、家庭電気製品、陶器、ガラス製
品、家具、果物、薬品、食品等の包装・緩衝材として用
いられる緩衝用シートに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cushioning sheet used as a packaging / cushioning material for precision machinery, household electrical appliances, pottery, glass products, furniture, fruits, medicines, foods, etc. .
精密機械、家庭電気製品、陶器、ガラス製品、家具、果
物、薬品、食品等を輸送する際、これらの品物を輸送中
の衝撃から守るため、各種の緩衝材が用いられる。When transporting precision machinery, household appliances, pottery, glassware, furniture, fruits, medicines, foods, etc., various cushioning materials are used to protect these items from shocks during transportation.
従来用いられてきた緩衝材としては、発泡スチロールの
ブロックや発泡ポリエチレンのシート、二枚のポリエチ
レンシート間に気泡を閉じ込めたシート（登録商標「エ
アーキャップ」）が主なものであった。As a cushioning material that has been conventionally used, a foam polystyrene block, a foam polyethylene sheet, and a sheet (registered trademark “air cap”) in which air bubbles are trapped between two polyethylene sheets are mainly used.
発泡スチロールのブロックや発泡ポリエチレンのシート
は、一般にポリスチレンやポリエチレンなどをブロック
やシートに成型前または成型中に発泡させる方法で主に
製造されてきた。また、ポリスチレン等のビーズを予め
発泡させ、発泡したビーズを型に入れて成型するという
方法でも製造されてきた。Styrofoam blocks and expanded polyethylene sheets have generally been produced mainly by a method of foaming polystyrene or polyethylene into a block or sheet before or during molding. It has also been manufactured by a method in which beads such as polystyrene are previously foamed and the foamed beads are put into a mold to be molded.
従って、これらのブロックやシートは発泡工程の分だけ
コスト高になるという問題があった。Therefore, there has been a problem that the cost of these blocks and sheets increases due to the foaming process.
加えて、これらのポリマーを発泡させるために用いられ
る発泡剤としては、ペンタンなどの低沸点炭化水素やフ
ロンガス、ジアゾ化合物などが一般に用いられてきた。
しかし、これらの発泡剤には使用の際に環境問題を引き
起こすものが多い。In addition, as a foaming agent used for foaming these polymers, low boiling point hydrocarbons such as pentane, fluorocarbons, and diazo compounds have been generally used.
However, many of these foaming agents cause environmental problems when they are used.
又、発泡スチロールのブロックは細かく砕けやすい上静
電気を帯びやすい。このため、精密機械等の梱包・輸送
中に、衝撃などで緩衝材の発泡スチロールブロックが砕
け、中身の精密機械等に付着するという問題もあった。Further, the styrofoam block is easily broken into small pieces and easily charged with static electricity. For this reason, there is a problem that the styrofoam block of the cushioning material is crushed due to an impact during packing and transportation of the precision machine and the like and adheres to the precision machine of the inside.
二枚のポリエチレンシート間に気泡を閉じ込めたシート
（登録商標「エアーキャップ」）には、このような問題
はない。しかし、輸送中の衝撃で気泡が破れ易く、気泡
が破れると緩衝材としての機能を殆ど果たさなくなる。A sheet having air bubbles trapped between two polyethylene sheets (registered trademark “air cap”) does not have such a problem. However, the bubbles are easily broken by the impact during transportation, and when the bubbles are broken, the function as the cushioning material is hardly fulfilled.
本考案は、上記の点に鑑み、安価に製造でき、輸送中の
