ていた。フィラー人ポリオレフィンを用いる理由として
、その剛性、耐熱性か良好なためである。BACKGROUND OF THE INVENTION Conventionally, for the above-mentioned applications, polyolefin sheets molded from filler polyolefin sheets of 30 to 40 layers have been used. The reason why filler polyolefin is used is because of its good rigidity and heat resistance.
本発明か解決しようとする問題点

すく、またフィラーの粉ふき現象があり、擦過傷が目立
ちやすい。また。Problems to be Solved by the Invention In the prior art, the filler was a single layer of polyolefin, so when it was used as a tray, it was likely to stick to food, and the filler would flake off, making scratches more noticeable. Also.
トレイに収納した粘着食品をステンレス製のヘラでスキ
ージする場合にトレイか摩耗しやすい等の欠点があった
。また、フィラーか直接食品と接する場合、フィラーか
食品中に溶出する危険かある。There was a drawback that the tray was easily worn out when squeegeeing sticky foods stored in the tray with a stainless steel spatula. Also, if the filler comes into direct contact with food, there is a risk that the filler will dissolve into the food.
本発明は１食品類のトレイ用として適した耐摩耗性か良

置して一体化した多層シートである。Means for Solving the Problems The present invention has been made to achieve the above objects.
It is a multilayer sheet in which a filler-free polyolefin layer is arranged on one or both sides of the filler-free polyolefin layer.
作用
本発明は上記の特徴を有することにより、表面層のノン

要な機械的強度と耐熱性を満足するものである。Function The present invention has the above-mentioned characteristics, and thus can ensure non-adhesiveness, scratch resistance, abrasion resistance, and food hygiene safety due to the non-filler polyolefin of the surface layer. Furthermore, the filler polyolefin layer satisfies the mechanical strength and heat resistance required for the tray.

Three layers of non-filler polyolefin are possible. In particular, the latter can be effectively used as a structure for suppressing warpage caused by the difference in mold shrinkage between non-filler polyolefin and filler polyolefin.

容易である点からも共押出か好ましい。Methods for producing the multilayer sheet of the present invention include coextrusion using a feed block, coextrusion using a multi-manifold die, or a method in which a single layer of filler polyolefin is extruded and a film of non-filler polyolefin is laminated. Coextrusion is preferred due to problems such as cost, dust adsorption due to static electricity during lamination, etc. Further, in the case of a coextruded three-layer sheet, coextrusion is preferred because it is easy to change the surface properties by changing the types of both surface layers, such as polypropylene/filler polypropylene/olefin elastomer.
