Abstract
A flexible sheet material and package formed therefrom is provided. The multilayer sheet material includes a first flexible heat sealable plastic material with antistatic properties on at least the one major surface thereof which first layer is laminated to a second flexible plastic material with an electrically conductive material on the one major surface thereof and antistatic properties on the other major surface thereof.
Claims26
A flexible sheet material adaptable for forming a package, bag, pounch, or the like for containing electrostatically sensitive components comprising:
- (a) a first layer of a flexible heat sealable plastic material having primary and secondary major surfaces with antistatic properties on at least said secondary major surface thereof;
- and
- (b) a second layer of a flexible plastic material having primary and secondary major surfaces with an electrically conductive material on said primary major surface and with antistatic properties on at least said secondary major surface, said first and second layers of material being bonded together along said primary major surfaces, respectively, of said first and second layere.
A package adapted to receive and protect an electrostatically sensitive component, the walls of said package formed of a flexible sheet material comprising:
- (a) a first layer of a flexible heat sealable plastic material having primary and secondary major surfaces with antistatic properties on at least said secondary major surface thereof;
- and
- (b) a second layer of a flexible plastic material having primary and secondary major surfaces with an electrically conductive material on said primary major surface and with antistatic properties on at least said secondary major surface, said first and second layers of material being bonded together along said primary major surfaces, respectively, of said first and second layers:
- said package being formed by joining together said walls along opposing side edges of facing secondary major surfaces of said first layers of flexible plastic material.
A thermoformed container adapted to receive and protect an electrostatically sensitive component, the walls of said container comprising:
- (a) a first layer of a flexible heat sealable plastic material having primary and secondary major surfaces with antistatic properties on at least said secondary major surface thereof;
- and
- (b) a second layer of a flexible plastic material having primary and secondary major surfaces with an electrically conductive material on said primary major surface and with antistatic properties on at least said secondary major surface, said first and second layers of material being bonded together along said primary major surfaces, respectively, of said first and second layers.
