摘要
在拉伸机上进行包装时，盖膜和底膜配套使用，底膜是具有热成型功能的，由于模具的长度是固定的，那么底膜在成型后的长度也是固定，所以对于盖膜的长度要求就非常高。本文详细分析了盖膜长度控制因素，提出从成品重复长度控制、版辊尺寸控制、生产过程控制入手，更好地控制复合盖膜的重复长度。
On the tensile machine for packaging, lid film can be used with the base film, which is of the thermoforming function. For the fixed length of the base film after molding, which is due to the fixed length of the mold, the demand to the length of the lid film is very strict. The control factors of the lid length are analyzed in detail in this paper, and how to better control the repeat length of composite lid film from the repeat length control of finished product, size control to the version of the roll and process control, was put forward as well.
