Abstract
The invention provides a cover tape and the method for manufacturing the same. The cover tape comprises an antistatic layer, two intermediate layers, a base layer, two tie layers and a heat seal layer. These seven layers are formed by a co-extrusion process.
Claims13
A method for manufacturing a cover tape, comprising the steps of:
- providing materials for forming a multi-layer film including an antistatic layer, a first intermediate layer, a first tie layer, a base layer, a second tie layer, a second intermediate layer, and a heat-sealing layer;
- providing extruders with each extruder corresponding one of the multi-layer and being fed with the material for forming the corresponding layer;
- and
- simultaneously heating the material within each extruder to form a single-layered molten film, melting and flattening the single layered molten films to a multi-layered film.
