Abstract
Description
Claims (6)
- 2. A method according to claim 1 wherein said contacting, metering, stretching and cooling steps are carried out at a speed between 200 and 500 feet per minute and said stretching is carried out to the extent of between 10 and 18 percent of the original film length.
- 3. A method according to claim 2 wherein the weight of said wax composition after said metering step is between 3 and 6 lbs. per ream.
- 4. A method according to claim 3 wherein said polyethylene film is between 0.001 in. and 0.0025 in. in thickness.
- 5. A method according to claim 4 wherein said polyethylene film has a surface which is treated to be receptive to fluid coatings.
- 6. A method for obtaining a dimensionally stable wax-coated polyethylene web suitable for use in high-speed packaging operations which comprises applying a molten petroleum wax composition to at least one surface of a polyethylene web having a thickness of between 0.0005 in. and 0.005 in., maintaining said wax coating in a molten state and said polyethylene web at a temperature between about 130* F. and the softening temperature of the polyethylene while mechanically stretching said coated polyethylene web in a machine direction by an amount between about 5 percent and 20 percent, and subsequently chilling said coated and stretched web to complete solidification of said wax composition coating.
- 7. A method according to claim 6 wherein said wax composition is applied to a surface treated polyethylene web traveling at between about 200 and 500 feet per minute, said coated polyethylene web being stretched by an amount between 12 percent and 15 percent.
