Embodiment Construction
[0013] On both sides of the inside of the upper opening of the plastic bag 4, a concave 2-shaped card device and a convex card device 3 are prefabricated respectively, both of which are made of plastic, so as to be bonded with the inside of the plastic bag by heat pressing or by using an adhesive (It can also be made into a whole in the bag-making process), the washing powder for sale is filled in the above-mentioned plastic bag 4, and it is heat-press sealed in the heat-press fusion zone 1. When opening the bag, opening between the thermocompression fusion sealing area 1 and the convex card device 2 and the concave card device 3 can achieve the purpose. The invention effectively overcomes the defect that the existing washing powder packaging bag cannot be closed after the gap is opened, which easily causes loss and waste of washing powder.

The invention provides a washing powder packaging bag, belonging to the technical field of package. A concave clamp device and a convex clamp device are respectively prefabricated at two sides in an upper opening of a plastic bag, the concave clamp device and the convex clamp device are made from plastics, and washing powder to be sold is filled in the plastic bag and is sealed in a hot-press way in a hot-pressing fusion zone. The bag can be opened only by opening between the hot-pressing fusion zone and the concave / convex clamp devices. The defect that the washing powder is easy to lose and waste since an opening on the existing washing powder packaging bag can not be sealed is overcome.
Description
technical field [0001] The invention relates to the technical field of packaging, in particular to a washing powder packaging bag. Background technique [0002] At present, the packing of washing powder all is to adopt common plastic bag, and washing powder is airtight in the plastic bag, and when using, a gap is cut in the airtight plastic bag, from which washing powder is poured out. Once the packaging bag of this structure is cut, the gap is in an open state. Since the washing powder cannot be used up at one time, the remaining washing powder may cause spillage or water ingress, resulting in loss and waste. . Contents of the invention [0003] The invention provides a packing bag for washing powder, which overcomes the defects of the existing packing bag for washing powder that the gap after opening cannot be closed, which easily causes loss and waste of washing powder. [0004] The beneficial effects of the present invention are: the present invention effectively ...
