Processing method and finished product of self-adhesive coin collection paper clip

Abstract

The invention discloses a self-adhesive coin collection paper clip processing method and a finished product thereof. The self-adhesive coin collection paper clip processing method comprises the following steps: forming symmetrical holes in the two sides of a paperboard impression through pressing, covering the holes with concentric PP films, and forming concentric circular impressions through pressing. After a paperboard is folded and adhered along the impressions, by utilizing the deformation bulges of the circular impressions, the influence of collected coin thickness on adhesive surface reactive force is effectively eliminated, the reliability of adhesion is guaranteed, and the durability of a paper clip is improved. Through the laminating design of double-faced holes, a collected coin is convenient to view from two surfaces; moreover, a good sealing property is also formed, the oxidation of the collected coin is prevented, the long-term collection requirement is met, and the paper clip is a good guarantee for coin collection.

Description

technical field [0001] The invention relates to a product for collecting coins, in particular to a method for processing a self-adhesive coin collecting paper clip which is convenient for viewing on both sides and fast packing and storing, and a finished product thereof, which belongs to the field of coin collecting products.

Problems solved by technology

Among them, the hard paper box is composed of a square box body and a soft base material with a circular pit embedded in it. The coin collection card is held in the circular pit. The packaging is firm, stable, and easy to carry. It is blocked and cannot be viewed from both sides, which seriously affects the viewing and collection effect

The plastic bag is made of polyethylene material, and the collection of coins can be directly sealed in the plastic bag, which is low in cost, easy to use, and easy to watch on both sides, but the polyethylene material is soft, poor in support, easy to wear, polluting, not environmentally friendly, and low in grade , which is inconsistent with the value and purpose of coin collection, is being phased out

The paper clip is a product that has appeared in recent years. It is made of hard paper material with a through hole in the middle. The collected coins are directly embedded in the through hole. This method is easy to watch the coins on both sides. At the same time, it is also easy to carry and economical , environmental protection, and beautiful appearance, but the existing paper clips have a poor holding effect, and it is not easy to repeatedly insert and pull out coins. The durability and stability are affected to a certain extent, which hinders the wide-scale promotion and use of paper clips.
