摘要
The mouth of a bag or sack is closed by joining together the ends of a pair of strips, wrapping the strip around the mouth of the bag, joining the strips around the other side of the neck, cutting them and simultaneously leaving them joined for the next bag. Joining may be by adhesive or seal-welding.
