Description

Laminated film with multilayer sealing film

Technical Field

The invention belongs to the technical field of laminated films, and particularly relates to a laminated film with multiple layers of sealing films.

Background

The lamination method refers to a method of integrating two or more layers of the same or different materials by heating and pressing, and the film is a thin and soft transparent sheet made of plastic, adhesive, rubber or other materials, and the scientific interpretation of the film is as follows: two-dimensional materials formed by atomic, molecular or ionic deposition on the substrate surface can be laminated at the edges during the lamination process, so that the final product has a multi-layer sealing film, which is a prior art.

However, the existing laminated film still has some defects in the using process: when the existing laminated film is used, the common laminated film is wound up by winding, and when the laminated film is needed to be used, a user cannot conveniently find the port in time, moreover, the prior laminated film has no device for a user to find the port, so that certain inconvenience is brought to the user when in use, the use is affected, meanwhile, the prior art has inconvenient tearing of the laminated film, and the manual tearing or the scissor tearing method is usually adopted, which wastes manpower and material resources too much, and the tearing process is too time-consuming, and the prior art also sets a breakpoint on the surface of the laminated film to achieve the effect of convenient tearing, but the integral strength and the sealing effect of the laminated film can not be ensured after the breakpoint is set, water leakage at the breakpoint is easy to cause, and even if the breaking point is arranged, when the tear is torn by a hand, the tear opening is still easily uneven, and the laminated film is wasted.

Disclosure of Invention

In order to make up for the defects of the prior art, solve the problems that a user cannot find a port conveniently in time when the laminated film is used, manpower and material resources are wasted too much by adopting a method of tearing with a hand or a method of tearing with scissors, time is wasted too much in the tearing process, a breakpoint is arranged on the surface of the laminated film, the integral strength and the sealing effect of the laminated film cannot be guaranteed, water leakage at the breakpoint is easily caused, and the tearing port is not flat and the laminated film is wasted even if the breakpoint is arranged when the laminated film is torn with the hand, the laminated film with the multilayer sealing film is provided by the invention.

The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to a laminated film with a plurality of layers of sealing films, which comprises a film main body and a positioning block, wherein the film main body comprises an inner layer, an outer layer and an intermediate layer; the middle layer is positioned between the inner layer and the outer layer; the surface of one side of the middle layer is provided with uniformly distributed grooves in a semicircular design; a corresponding through hole is formed below each groove; tear lines which are uniformly distributed are arranged in the middle layer; the tearing lines are arranged corresponding to the grooves, and two tearing lines are arranged in each groove; one end of the tearing line, which is far away from the groove, penetrates through the corresponding through holes; easy-to-tear films which are uniformly arranged are fixedly adhered to the upper surface of the middle layer; the easy-tearing film is an easy-tearing PET film; the easy-to-tear films are arranged in one-to-one correspondence with the grooves and are used for covering the grooves, so that one side of the middle layer provided with the grooves is smooth; when the film tearing device works, according to the length of a required film main body, a proper groove is selected, after an easily torn film corresponding to the groove is torn, two tear lines are manually grabbed, the tear lines are pulled in the opposite direction, the film main body can be effectively torn through the tear lines, time and labor are saved, the problems that in the prior art, when the film is cut off by scissors, more tools are carried in outdoor work, and the cutting is time and labor consuming are solved, meanwhile, the problems that manual tearing is caused, the tearing opening of the film main body is uneven, the use is influenced, and the waste of the film main body is caused are solved, meanwhile, the resistance of the tear lines can be effectively reduced through uniformly arranged through holes, the film tearing device is simple and convenient to operate, time and labor are saved, through the arrangement of the inner layer, the outer layer and the middle layer, the strength of the film main body can be effectively improved, meanwhile, the through holes are covered and sealed, water leakage is prevented, and the problem that in the prior art, a breakpoint is arranged on the film main body is effectively solved, although the effect of easy tearing is achieved, the strength and the waterproof performance of the film body are seriously influenced.

Preferably, the positioning block is arranged at one end of the film main body, a connecting groove is formed in the positioning block, fixing grooves are formed in two sides of the connecting groove relative to the inside of the positioning block, and clamping pieces are fixed in the fixing grooves in a clamping mode; when the film body is used, a user can push the positioning block until the film body on one side of the positioning block is used sufficiently, tear the easily torn film, divide the film body into two parts through the tear line, and use one part which needs to be used; through the clamping piece, utilize the clamping piece to meet with the film main part, utilize the clamping piece to the extruded effect of film main part, increase the frictional force between clamping piece and the film main part, thereby avoid locating piece and film main part to break away from, and the locating piece of being convenient for can remove along the film main part under the effect that the user promoted, thereby the person of being convenient for fixes a position the tip of film main part, effectively prevent that the film main part from causing the tip to look for the difficulty when using once more after accomplishing, thereby effectively improve the operating efficiency, prevent when the tip of film main part can't be found, destroy other parts of film main part, cause the waste of film main part, and waste time and energy.
