Flexible vertical form, fill, seal packaging material and method of using |
摘要 |
Flexible packaging material suitable for making peelable form-fill-seal packages of the "pillow" type comprises a paper web which is coated with a normally non-tacky pressure- or heat-activatable adhesive and which is treated with a composition having release properties with respect to the adhesive, e.g. by means of a size press. The release composition is preferably a polysiloxane, an organo-chromium stearate complex, a ketene dimer or a paper fluoridizing agent.
