Abstract
The utility model relates to an inner folding type bottom sealing bag with curves. The utility model is characterized in that one end of an envelop is provided with more than one curve sealing lines or arc line type sealing lines. The utility model has the advantages that as curve type or arc line type sealing are adopted, and the stress direction of the original straight line type sealing is changed; the capability of shock resistance of the sealing is raised; under the impact of materials, the sealing can not be easily cracked when the materials are loaded in the bag. As a machine is used for sealing the bag, the sealing can be uniformly connected and is shapely and decent.
Description
The utility model relates to a kind of interior folding curve back cover bag.
The employed pocket of existing artificial cultivating in bag edible mushroom is to adopt linear pattern to seal, and this linear pattern is sealed pocket at when filling with substance, and sealing part breaks easily owing to be subjected to the impact of material, makes troubles to use.
The purpose of this utility model is to provide a kind of and seals firmly, and sealing part can tolerate bigger impact and the interior folding curve back cover bag that is difficult for breaking.
The technical solution of the utility model is as follows: an end of bag is provided with one or more curve or arc line type sealing line.
The utility model has the advantages that: owing to adopted curve or arc line type to seal, changed the force direction that is subjected to that original linear pattern seals, thereby improved the ability that the sealing part opposing is impacted greatly, made this bag not allow to be subject to the impact of material and break at the when filling with substance sealing part.And owing to adopt machine to seal, sealing part is connected evenly, elegant in appearance.
