PURPOSE:To provide an easy handling in component mixing operation, maintain the accurate mixing ratio and prevent the pollution of operating environment by placing an easily breakable inner bag containing separately each of the second and subsequent components into a flexible packaging bag containing any first component. CONSTITUTION:A flexible packaging bag in the form commercially available is normally used as such and, as its base material, the film or sheet normally in use is used as such without being restricted in the usage. As the base material for use for an easily breakable inner packaging bag, it is preferable to use the plastic film formed of a mixture of the resins consisting chiefly of a 40-90wt.% or ethylene (co)polymer and/or propylene (co)polymer referred to as A and a 10-60wt.% of styrene (co)polymer referred to as B (with the proviso that A plus B is 100%). This plastic film for use as the base material for the easily breakable inner bag is formed by a T-die extrusion molding and inflation method using the composition mixed with an additive agent normally in use for the plastic molding. |
