Description
Technical field
A kind of packaging product the present invention relates to diaphragm seal and using the diaphragm seal.More particularly to use specific adhesive
, there is specific opening ways or the diaphragm seal with being combined using the Thermal-printing Technology of UV solidifications then glue.
Background technology
With the development of packaging field, the packaging product of the miscellaneous needs for meeting different industries emerges in an endless stream.Often
Make in the packed flexible packaging industry seen, the can pack field of various materials, industrial products packaging field, building packaging field etc.
Sealed membrane is different, and false proof, nontoxic, high-low temperature resistant, resistance to boiling, anti-quiet is typically included to the performance requirement of diaphragm seal
Electric, transparent/opaque, resistance to broken, waterproof, airtight/ventilative, antiultraviolet, printable texts and pictures etc., are needed to the performance of adhesive
Ask and be divided into PUR, pressure by bonding principle including processing characteristics, initial bonding strength, holding power, peeling force, nontoxic, colourless etc., adhesive
Quick glue, UV solidification glues or its combination etc..
Realized using adhesive diaphragm seal and diaphragm seal or diaphragm seal and glass, metal, plastics, paper etc. adhesion it
Afterwards, when carrying out the stripping of diaphragm seal, on the premise of adherend is not destroyed, common includes following three kinds stripping modes：
(1) delamination：Layering failure is called, when referring to tear diaphragm seal, the sealant of film occurs with other composite beds
It is layered and is peeling, sealant is stayed in adherend.Under such a stripping, the sealant of diaphragm seal and adjacent thereto compound
The compound fastness of layer is less than sealant and the sealing intensity of adherend, so point of sealant and composite bed occurs when peeling off
Layer, and sealant is relatively thin, is easy to break to form layering, and peeling force size is difficult to control, and when opening diaphragm seal, is easily had
Phenomena such as wire drawing, band burr.
(2) interface peel：Interfacial failure is called, when referring to tear diaphragm seal, the sealant of diaphragm seal can be from being attached
It is completely exfoliated on thing.After diaphragm seal is peeled off, diaphragm seal and adherend do not have obvious color, transparency change, are glued
The stripping surface of addendum is clean, neat, attractive in appearance.This stripping mode is the easily revealed secrets sealer such as current many jelly, Yoghourt, puddings
Stripping mode, but the size of its peeling force influenceed by condition when sealing it is bigger, seal window relative narrower, be subjected to
After autoclaving process, diaphragm seal i.e. can Automatic-falling, stripping.
(3) cohesion is peeled off：Cohesion failure is called, when referring to tear diaphragm seal, the sealant of diaphragm seal first produces interface and broken
Internal stripping badly occurs, itself is destroyed, and a sealant part is stayed in diaphragm seal main body, and another part, which has then stayed in, to be glued
Addendum surface, after diaphragm seal is peeled off, stripping vestige is clearly white, and peel strength is generally relatively low.
And bonded joint bear external force and it is destroyed when, be divided into and stick destruction and (occur on the interface of glue-line and adherend
Destroy), cohesional failure (glue layer destroys), mixing destroy (stick destroy and cohesional failure have), adherend itself
Destroy (cohesive force that the cohesive force of adherend is less than adhesive strength and glue-line) etc..

When opening, user, which grips, draws ear 1-2-1 to start to peel off, first from the first weak bonding in the first peel ply 1-3
First stage stripping occurs for agent 1-3-2 right side, and stripping stops after extending to the first strong bonding agent 1-3-1, i.e. the first stage shells
Stop from rest position is peeled off first；Ear 1-2-1 is drawn when user pulls on, under the involving of the first sheet material 1, with the first stripping
Corresponding from rest position first, which peels off guiding space 2-3-G, may proceed to guide the second peel ply 2-3 to occur the from the position
Two-stage is peeled off, and second stage is peeled off to be extended to the left and right, and second stage peels off the left side and completes to peel off prior to the right, second stage stripping
From the right extend to the second stripping rest position when stop；Ear 1-2-1 is drawn when user pulls on, in the first sheet material 1 and the
Under the involving of two sheet materials 2, corresponding with the second stripping rest position second, which peels off guiding space 3-3-G, may proceed to guiding the 3rd
From the position phase III stripping occurs for peel ply 3-3, and phase III stripping extends to the periphery diaphragm seal SM and adherend C
Separate, complete to peel off.Wherein, it is delamination or interface peel or the group of cohesion stripping or aforesaid way to peel off mode
Close.
In stripping process, all sheet materials are covered on adherend C, to reach protection bur C effect, until stripping
From completion.As in the present embodiment, the second functional layer 2-1 and the 3rd functional layer 3-1 have antistatic performance, ensure stripping process
In caused electrostatic will not be passed in adherend C, and then avoid it is caused electric discharge damage, until peel off complete.
