摘要: This process of molding a thermoplastic sheet can be used for blister packaging.
The process particularly includes the premolding step of bringing the sheet into close contact with the outer cylindrical surface of a molding drum, preheating the sheet and concurrently vacuum sucking the sheet into a cavity defined on the outer cylindrical surface of the drum; and the full-molding step of vacuum sucking the sheet and concurrently inserting the sheet into the cavity by means of a plug.
The process can well mold a thermoplastic sheet including a layer of polypropylene.摘要翻译: 这种热塑性片材的成型方法可用于泡罩包装。 该方法特别包括使片材与成型鼓的外圆柱形表面紧密接触的预成型步骤,预热片材并且同时将片材真空吸附到限定在鼓的外圆柱形表面上的空腔中; 以及真空吸附片材并通过插头将片材同时插入腔体的全成型步骤。 该方法可以很好地模制包括聚丙烯层的热塑性片材。
