A flexible thermoformed dispensing package for a flowable material that can be massed produced on a horizontal thermoform-fill-seal (HTFFS) machine includes a container portion that is dimensioned and configured with a flat self-supporting base, integral opposing side walls and a rear wall extending from the base, and a top wall or seam integrally formed from a single sheet or web, the side walls tapering from the base toward the integral rear wall and terminating at the top wall or seam; and a front wall that is heat-sealed as a separate sheet to the periphery of the periphery of the base, side walls and top wall to form a fluid-tight package that maintains a stand-up orientation when in use, and optionally includes an integral dispensing tube with an optional internal extension terminating proximate the supporting base for withdrawing liquid contents from the package.

The invention relates to a graphene-copper composite heat dissipation film and its preparation method and application. The preparation method comprises the following steps: firstly pretreating natural graphite, and then successively undergoing high-speed shearing, ultrasonic stripping and emulsification to obtain graphene; The graphene is mixed, then prepared into a film and dried to obtain a graphene film, and then the graphene film is heated at a preset temperature to prepare a micro-airbag, and then the micro-airbag is mechanically rolled at a preset pressure to Prepare micro-folds; compact the graphene film and copper foil, and then paste the thermally conductive black film on the other side of the copper foil to obtain a graphene-copper composite heat dissipation film. The preparation method of the graphene-copper composite heat dissipation film of the present invention accelerates the dissipation of heat by balancing the point-like heat source to the surface, and then radiates it longitudinally, so as to achieve the protection effect of product components, and its heat dissipation effect is better than that of traditional Craft graphite flakes and artificial graphite flakes.

The invention relates to an oblique pressing machine for flattening trademarks, which includes a frame, on which a printing mechanism and a die-cutting mechanism are arranged, and on the said frame, an oblique pressing machine for carrying and conveying self-adhesive label tapes is provided. Flat seesaw, the obliquely pressed flat seesaw is adapted to the printing mechanism and the die-cutting mechanism, one end of the obliquely pressed flat seesaw is hinged to the head end of the frame through a hinged frame, and the other end is hinged to the tail of the frame end, the conveying self-adhesive label tape is conveyed from the head end to the tail end of the frame through the surface of the oblique flat seesaw through the paper pulling mechanism in the frame. The side is inclined to the ground, and the frame is provided with a drive mechanism for driving the end of the oblique pressing flat seesaw to move up and down. The invention has the effects of improving the mold clamping quality and indirectly improving the printing and die-cutting quality.

The invention discloses a shielding and grounding conductive foam adhesive tape with metal foil as the base material, which comprises: shielding and grounding conductive foam, a hot melt adhesive layer, a metal foil base material, Conductive adhesive layer, release material layer. Also disclosed is a preparation method of a shielding and grounding conductive foam tape, which has high conductivity, better electromagnetic shielding function, better die-cutting, and less There will be fuzz problems similar to conductive cloth. Compared with using ordinary conductive pressure-sensitive adhesive to bond the foam to the substrate, the foam has better resilience, which solves the problem of poor rebound when the foam is stuck by the glue during die-cutting or use.
