Description

  The present invention relates to the shape of a roll roll hand wound roll holder.

  Conventionally, stretch films have been used to prevent the collapse of packages loaded on pallets. The stretch film is lightweight, has a tensile strength, and an adhesive force increases when it contracts by pulling. Therefore, the package is fixed and is a material suitable for preventing the collapse of the package.

  This stretch film has a mass per roll of stretch film of about 2.5 kg to 6.5 kg depending on the type of material and the thickness, length and width of the material for each manufacturing company. The inner diameter of the paper tube that winds up the paper also varies from 76 mm to 77.2 mm.

  The basic procedure for using stretch film is to first squeeze the end of the stretch film into a part of the package, hold the roll of stretch film with both hands, and roll the stretch film around the package. -Rotate the reel and wind the stretch film around the packing material so that it is rewound. In general, a package to be loaded on a pallet is stacked with a height of about 150 cm to 170 cm.

  Also, during the work of winding the stretch film around the package, temporarily stop the rotation of the stretch film, pull the stretch film and draw out the elasticity that is characteristic of the stretch film and the adhesive force when shrinking, The wrapping force is increased, and the package is stabilized by suppressing the shaking of the package.

  In the operation of stacking the packages, usually rubber-coated gloves are used to facilitate handling of the load because of protection of hands, protection against cold, moisture, and a large frictional force with the package. However, when the roll of the stretch film is rotated and used, there is a situation that this large frictional force is a factor of lowering work efficiency.

  Until now, many auxiliary tools for using a stretch film have been developed.

  Conventionally, stretch films have been used to prevent the collapse of packages loaded on pallets. The stretch film is lightweight, has a tensile strength, and an adhesive force increases when it contracts by pulling. Therefore, the package is fixed and is a material suitable for preventing the collapse of the package.

  This stretch film has a mass per roll of stretch film of about 2.5 kg to 6.5 kg depending on the type of material and the thickness, length and width of the material for each manufacturing company. The inner diameter of the paper tube that winds up the paper also varies from 76 mm to 77.2 mm.

  The basic procedure for using stretch film is to first squeeze the end of the stretch film into a part of the package, hold the roll of stretch film with both hands, and roll the stretch film around the package. -Rotate the reel and wind the stretch film around the packing material so that it is rewound. In general, a package to be loaded on a pallet is stacked with a height of about 150 cm to 170 cm.

  Also, during the work of winding the stretch film around the package, temporarily stop the rotation of the stretch film, pull the stretch film and draw out the elasticity that is characteristic of the stretch film and the adhesive force when shrinking, The wrapping force is increased, and the package is stabilized by suppressing the shaking of the package.

  In the operation of stacking the packages, usually rubber-coated gloves are used to facilitate handling of the load because of protection of hands, protection against cold, moisture, and a large frictional force with the package. However, when the roll of the stretch film is rotated and used, there is a situation that this large frictional force is a factor of lowering work efficiency.

  Until now, many auxiliary tools for using a stretch film have been developed.
