摘要： A multilayer polyolefin film for use as an electronic cutter film is disclosed. The film provides improved abrasion and graffiti resistance, and adhesive anchorage versus a comparable single layer film while still maintaining excellent cutting properties. The film also shows excellent resistance to "surface impressions", which are a major problem for traditional vinyl-containing electronic cutting films.
摘要翻译： 公开了用作电子切割器膜的多层聚烯烃膜。 该膜与类似的单层膜相比提供了改进的耐磨和耐涂抹性，以及粘合剂锚固，同时仍保持优异的切割性能。 该薄膜还表现出优异的抗“表面印痕”，这是传统含乙烯基电子切割薄膜的主要问题。

摘要： A web (10) of material has a plurality of stems (12) extending from at least one side of the web. The web includes a first layer (14) of material having a first side and a second side and a second layer (16) of material. The second layer of material has a first side which faces the first side of the first layer and a second side from which the plurality of stems extend. The first and second layers of material are joined together while they are both molten, before either layer has cooled. The first and second layers of material can be formed of thermoplastic material or melt processable polymeric material. A method of making a web of material includes selecting a first material for a first layer of material and selecting a second material for a second layer of material. The first and second layers of material are melt formed. Then, the first and second layers of material are joined while the layers are in the molten state to form a multiple layer sheet. Next, a plurality of stems are formed on at least the second layer of material. Melt forming can include simultaneously melt forming the first and second layers of material such as by coextrusion.
