More particularly, it relates to a film or sheet having excellent oil and fat impermeability, which comprises a layer of poly-4-methyl-1-pentene having a melting point of 190 to 230 ° C. and a layer of paper, and a carton made therefrom.
（従来の技術及びその問題点） 最近、電子レンジによる調理方法が急速に進歩普及
し、多種類の料理や菓子などの食品の調理が極めて手軽

食品を収納して高周波による加熱が行われる。When cooking food in a microwave oven, for example, the food for cooking is stored in a tray-like container formed from a laminated sheet of an inner layer made of a 4-methyl-1-pentene polymer and an outer layer made of paper, and is subjected to high frequency. Heating is performed.

There is a case in which cooking is completed by heating, but after heating with a microwave oven or after applying a sauce containing an oil and fat component after the heating, it may be stored in a box-shaped container.

を油脂成分で汚される可能性がある。However, since the coating layer of the 4-methyl-1-pentene polymer which has been used conventionally has high rigidity, fine cracks may occur in the coating layer. In such a case, The oil and fat component permeates the paper layers that make up the container with the passage of time, and the entire paper layer becomes oily paper, impairing the appearance of the container, and the hands and clothes can be contaminated with the oil and fat components during handling. There is a nature.

MFRは５乃至1000g/10分のものが好適であるが、なかで
も、70乃至300g/10分のものが成形性、耐熱性に良好な
点で特に好ましく使用することができる。(Explanation of a preferred embodiment) In the present invention, the poly-4-methyl-1-pentene is a homopolymer of 4-methyl-1-pentene, or 4-methyl-1-pentene, and usually 20 mol% or less, preferably Is 12 mol% or less of another α-olefin, for example, ethylene, propylene, 1-butene, 1-hexene, 1-
It is a copolymer with an α-olefin having 2 to 20 carbon atoms such as octene, 1-decene, 1-tetradecene, 1-octadecene and has a melting point of 190 to 230 ° C, preferably 200 to 2
Crystalline poly-4-methyl-1-pentene at 30 ° C. is preferably used, and this polymer can be produced by a method known per se, for example, the method described in JP-A-59-206418. High melting point poly 4-methyl-1-pentene
The MFR is preferably from 5 to 1000 g / 10 min, but of these, from 70 to 300 g / 10 min is particularly preferable because it has good moldability and heat resistance.

した融点のポリ４−メチル−１−ペンテンを得ることは
当業者にとって容易なことである。Generally, the melting point decreases with an increase in the amount of α-olefin to be copolymerized, but it is also affected by factors such as the type of α-olefin, the catalyst used, and other polymerization conditions. However, since the relationship between these factors and the melting point can be determined experimentally in advance, it is easy for those skilled in the art to obtain poly-4-methyl-1-pentene having the intended melting point.

ものである。Thus, by laminating a layer of poly-4-methyl-1-pentene having a relatively low melting point of 190 to 230 ° C. with a layer of paper, the fat and oil component penetrates into the layer of paper even when heated by a microwave oven. Therefore, it is possible to provide a laminated film or sheet suitable as a container material.

場合にも、好適な印刷基材となる。Further, as the paper constituting the other layer, clay coated paper, milk carton paper and the like which are usually used as a box-making material are used.
-When the pinten layer has a pinhole or a slight crack due to an unexpected impact or abrasion from the outside, or a case where the oil component penetrates from the end surface of the laminated sheet. However, it is recommended to use clay-coated paper because the penetration of fats and oils is extremely slow.Since this clay-coated paper has excellent printability, a printing layer may be provided on the outer surface of the container if necessary. When formed, it is also a suitable printing substrate.

-Pentene has excellent extrusion coating properties at high speeds, so that it is possible to perform extrusion coating at high speeds using ordinary extrusion coating processing equipment, which results in mechanical properties as well as interlayer adhesion. An excellent laminated sheet is obtained, but when extrusion coating is performed, by blowing gas such as air or nitrogen gas to both ends of the film-like material, neck-in and waving of both ends of the film-like material are improved. In this case, preferably, in the vicinity of the film-like material in contact with the base material, by blowing gas from the side where the film-like material does not contact the base material, more stable and at high speed. Extrusion coating is achieved.

好ましい。As a method of blowing gas onto the film-like material, specifically, for example, a metal pipe such as an aluminum pipe or a copper pipe, or a conduit such as a thermoplastic resin pipe is arranged downstream of the die, and the gas is supplied from the pipe to the poly 4- tube. A method in which a film-like material of methyl-1-pentene is sprayed at an arbitrary position while being extruded from a die and in contact with a substrate, preferably in the vicinity of a contact point where the film-like material is coated on the substrate, may be used. The pressure of the gas at the time of spraying is appropriately determined in consideration of the thickness of the film-like material to be coated, but it is usually in the range of 0.5 to 5 kg / cm 2 G. The diameter of the tip of the nozzle to be sprayed is usually in the range of 1 mm 2 to 50 mm 2 , preferably 5 mm 2 to 10 mm 2 . The distance from the tip of the nozzle to the film-like material is usually in the range of 2 mm to 100 mm, preferably 5 mm to 20 mm. Furthermore, it is preferable that the tip of the spray nozzle is directed from the inside to the outside of the film-like material, because the film-like material is expanded by the blown gas and the effect of narrowing the neck-in is further increased.

-II: manufactured by Perkin Elmer Co., Ltd.), the sample was melted at 260 ° C. for 5 minutes, cooled to room temperature at a rate of 20 ° C./min, crystallized and kept at room temperature for 1 minute, and then heated at a rate of 10 ° C./min. It is a peak temperature when an endothermic curve is measured. Poly 4 used in the present invention
One or more endothermic peaks of -methyl-1-pentene may be detected, in which case the maximum peak temperature is taken as the melting point.
