Fig. 5 is the cut-open view of another embodiment of the utility model self check protection label;

Fig. 6 is the use synoptic diagram of another embodiment of the utility model self check protection label.

Seeing also Fig. 1, the utility model self check shown in Figure 2 protection label first embodiment, is to make this protection label under normal involution state, does not appear the character and graphic mark or its array configuration that are implied, just exposes the figure of being remembered after being unlocked.This label is made of a transparent plastic film body 1, one low sticky limit ink printing layer 2, one high sticky limit ink printing layer 3, a pressure sensitive adhering agent layer 4 and an off-style paper layer 5.

This transparent plastic film body 1 is to be made by the plastic foil of suitable thickness; its transparency can perceive its bottom body that is covered; this film body can need be cut into the size shape of institute palpus specification according to food containers as the involution body layer usefulness of protection label, is to be rectangular coiling shape when making in a large number.

Should low sticky limit ink printing layer 2 be according to character and graphic mark or its combination of selecting design, directly carry out ink printing with toppan printing in the one side of above-mentioned transparent plastic film body 1, KK KK literal as shown promptly is selected font, after being printed in plastics film body 1, this literal KK KK promptly remembered, this layer color of the color matching of certain selected printing ink and transparent plastic film body 1 has difference, can be perceived for 1 layer by the plastics film body.The batching composition ratio of this ink lay is: printing ink KK-999 35% adds thinning agent 60% and adds 5% adjuvant again, Application of Additives is to engage for making the ink printing layer 2 and the contact interface of plastics film body 1 form low sticky limit, and 1 of plastics film body is gone up the zone 22 except that the ink printing layer 2 of KK KK literal, does not have the printed layers such as printing ink KK-999 of above-mentioned allotment.

The ink printing layer 3 of this high sticky limit is the covered type ink printing, directly be printed on the ink printing layer 2 of above-mentioned low sticky limit, no any character and graphic own, its selected ink colors is identical with the text color of low sticky limit ink printing layer 2, so after high sticky limit ink printing layer 3 is printed on above-mentioned ink printing layer 2, color is unified, originally be the ink printing layer that blank zone 22 has now scribbled high sticky limit, literal KK KK by plastics film body 1 perspective now disappears:: printing ink KK-998 35% adds thinning agent 65% and the batching composition ratio of this layer is, the selection of printing ink should make ink printing layer 3 form engaging of high sticky limit with the contact interface of plastics film body 1, in other words, the ink printing layer 2 that former regional 22 3 couples of literal KK of the ink printing layer KK that scribble scribble is high than the adhesion strength at plastics film body 1 interface.

This pressure sensitive sticker 4 is coated on the ink printing layer 3 of above-mentioned high sticky limit, is to belong to a kind of colourless pressure sensitive adhesives, adheres on the article for the protection label, and its batching composition ratio is: sticker kk-7131 55% adds thinning agent 45%.

This off-style paper layer 5 is to belong to a kind of protection ply of paper; be intended to protect the cementing agent of above-mentioned pressure sensitive adhering agent layer 4; so protection ply of paper and adhering agent layer 4 are fitted; tear during for ease of use and get; one composition surface of protection ply of paper is coated with a mould release; make the clinging power minimum of the contact interface of off-style paper layer 5 and pressure sensitive adhering agent layer 4, be convenient to both and tear off.Certainly adhesive layer 4 is not minimum with the cohesive force of waiting to seal the product base material.

Design according to the utility model the foregoing description makes: transparent plastic film body 1 is F with the adhesion strength of low sticky limit ink printing layer 2 ₁₂, transparent plastic film body 1 is F with the adhesion strength of high sticky limit ink printing layer 3 ₁₃, low adhesion strength ink printing layer 2 is F with the adhesion strength of high adhesion strength ink printing layer 3 ₂₃, high sticky limit ink printing layer 3 is F with the adhesion strength of pressure-sensitive adhesive layer 4 ₃₄, pressure-sensitive adhesive layer 4 is F with the sticky limit of off-style paper layer 5 ₄₅, then the adhesion strength of each bed interface has following design relation: F ₄₅＜F ₁₂" F ₂₃≈ F ₃₄" F ₁₃But if pressure-sensitive adhesive layer 4 is F with the adhesion strength of being pasted base material ₄₆The time, then the sticky limit of each bed interface is converted to following mutual relationship: F ₁₂" F ₂₃≈ F ₃₄≈ F ₄₆" F ₁₃The adhesion strength minimum of ink printing layer 2 and plastics film body 1 as can be known.

The application scenarios of the foregoing description as shown in Figure 3; Fig. 3 a situation (off-style paper layer 5 has been replaced) when not torn that is expression protection label with being pasted that base material 6 is fitted; because height adhesion strength ink printing layer 2; 3 essential ink colors is unified; so only can have an X-rayed printed layers 2 by plastics film body 1; 3 essential ink colors; when the base material 6 that labeled from food containers is torn when protecting; because the adhesion strength minimum of ink printing layer 2 and plastics film body 1; so both are (2 years old; 1) promptly separates; because the ink printing layer 2 former literal KK KK printed words that is printed on; so display; and plastics film body 1 is very big with the sticky limit of ink printing layer 3; still remain with regional 22 parts; just zone 22 presents essential ink colors, but literal KK partly then has been blank Transparent color.So the label of food containers is in case destruction can be reflected destroyed sign by label itself.

At label is from being pasted under the situation of fitting again after base material 6 is torn, because ink printing layer 2 is separated by plastics film body 1, when forcing both are fitted again, it is not good that it engages the density utmost point, so font KK is still being remembered, once torn off part still as Fig. 3 b manifests.

Fig. 4, the utility model protection label second embodiment shown in Figure 5 make this protection label under normal involution state, appear the character and graphic on it, and when just no longer being manifested by the character and graphic of memory after breaking a seal.This label include a transparent plastic film body 1 ', a low sticky limit ink printing layer 2 ', a pressure-sensitive adhesive layer a 4 ' and off-style paper layer 5 ' constitute, the characteristic of affiliated each layer is identical with first embodiment with design parameter, so do not give unnecessary details, just the mutual relationship of the sticky limit of each bed interface: F at this _{4 ' 5 '}＜F _{1 ' 2 '}" F _{2 ' 4 '}≈ F _{1 ' 4 '}, be converted to and the adhesion strength relation of being pasted base material 6: F _{1 ' 2 '}" F _{2 ' 4 '}≈ F _{1 ' 4 '}F _{4 ' 6 '}

See also Fig. 6; Fig. 6 a is the situation of expression protection label when not torn; since pressure-sensitive adhesive 4 ' be colourless; so literal KK is by printing ink seal layer 2 ' display; when label is torn because ink printing layer 2 ' with plastic foil 1 ' the sticky limit minimum, so both separation; ink printing layer 2 ' on literal KK just disappear, available thus memory disappears and judges that encapsulation goes to pot.
