摘要： The present invention is directed to a heat-shrinkable, thermoplastic film or bag which contains at least one homogeneous ethylene alpha-olefin copolymer with at least some limited long chain branching. Oriented films made in accordance with the present invention exhibit improved processability as well as improved physical properties such as excellent optics and impact resistance. A homogeneous ethylene alpha-olefin with long chain branching may be present in a monolayer film either alone or in a blend or may be included in one or more layers of a multilayer film in accordance with the present invention.

摘要： An oriented heat shrinkable film includes a layer including a multicomponent ethylene/alpha-olefin interpenetrating network resin having a melt index less than 1.4, the resin including a homogeneous component having a melt index of less than 1, and a density of at least 0.91 grams/cubic centimeter, and a heterogeneous component with a melt index of between 1.5 and 20; the film having a haze value (ASTM D 1003-95) less than or equal to 5, a peak load/mil value (ASTM D 3763-95a) of at least 155 newtons/mil, and a free shrink (ASTM D 2732-83) at a temperature of 200° F. of at least 8% in either or both of the longitudinal and transverse directions. Films with substantially balanced free shrink are preferred, in particular those with a free shrink balance of less than or equal to 30%. Advantages in downgauging and/or mechanical properties are provided without substantially adversely affecting properties such as free shrink and optics.

摘要： A method includes the steps of providing a tubing having an inner annular layer comprising a crosslinked polymeric material, and an outer annular layer comprising a non-crosslinked polymeric material, or a material that is crosslinked to a lesser extent than the material of the inner layer; longitudinally slitting the tubing to form a folded film; and reverse centerfolding the folded film to provide a folded film having a lateral slit edge, and a lateral folded edge opposite said lateral slit edge, such that the inner annular layer becomes an outer layer, and the outer annular layer becomes an inner layer. A bag can be made from the reverse centerfolded film, and an article such as food can be packaged in the bag.
摘要翻译：一种方法包括以下步骤：提供具有包含交联聚合物材料的内环形层的管道，以及包含非交联聚合物材料的外环形层，或者与内层材料交联程度较小的材料 ; 纵向切割管道以形成折叠膜; 并且折叠折叠折叠膜，以提供具有横向狭缝边缘的折叠膜和与所述横向狭缝边缘相对的侧向折叠边缘，使得内部环形层变成外层，并且外部环形层变成内层。袋子可以由反向折叠的薄膜制成，并且诸如食物的物品可以包装在袋子中。
