Innovative BlockTop Closure System

The BlockTop closure system is already being utilised in a host of packing rooms around the world where is helping to produce uniform square shaped bags; that are hygienically closed; yet easy to open. BlockTop also helps to optimise bag sizes and provide bag cost purchasing saving opportunities.

Used in conjunction with Chronos BTH Bottom-up filling systems, BlockTop provides total bag control throughout the closing process. Once filled the bag top is pre-cut, creased, double folded and hot melt glue is applied between the folds. The bag top is then pressed to spread the glue. Each closed bag top is folded over and further glue applied. The folded bag top is pressed onto the filled bag to form a square shaped bag.

BlockTop sealed bags are easy to open, by simply pulling across the top of the bag, which in then unrolled. As an added advantage the bag top can be re-folded to close it again.

A further advantage of utilising the BlockTop closing system is that the resulting filled bags are an ideal shape for optimum palletising and subsequent stretch hooding. When enhanced closure security is required BlockTop has the flexibility to be used in conjunction with conventional sewn closure systems.
