用于包装的增强拉伸膜。
专利摘要
一种拉伸膜，包括由可拉伸塑料膜材料制成的基膜、在基膜中沿主方向排列成多列的多个孔、以及至少一个由可拉伸塑料膜材料制成的增强条。增强条布置并固定在基膜上，位于两个相邻孔列之间的区域中。基膜的厚度大于或等于增强条的厚度，并且增强条的宽度（w）尽可能大，但使得增强条不接触或重叠相邻孔列中的孔。增强条可以固定到基膜上，使得与基膜不可分离且不可区分。
Original abstractA stretch film comprising a base film made of a stretchable plastic film material, a multiplicity of holes in the base film arranged in several columns along a main direction, at least one reinforcement strip made of a stretchable plastic film material. The reinforcement strip is arranged and fixed on the base film in an area between two adjacent columns of holes. The thickness of the base film is greater than or equal to the thickness of the reinforcement strip and the width (w) of the reinforcement strip is as great as possible, but is such that the reinforcement strip does not contact or overlap the holes in the adjacent columns of holes. The reinforcement strip may be fixed to the base film so as to be inseparable and indistinguishable from the base film.
