Annex good sample to test fixed in plastic anti-theft caps sealing performance test apparatus. Seal Tester has a sample holder can be easily fixed firmly fix the sample in the experimental apparatus, to avoid erratic movement of the pressing force in the process.

Because the sealing performance is related to the quality of the content and
save time. However, the sealing performance of plastic bottle caps and is an
important factor in the impact of plastic packaging containers, so in recent y
ears, concern about the sealing performance of plastic caps and bottle detecti
on much of the industry.
Only part of the sealing cap of the container, but its detection is important i
n sealing performance, and here we analyze the reasons for the importance c
ap sealing performance test. Standard barrier properties of packaging material
s will directly affect the shelf life of the product, in terms of the conventional
barrier properties of the container, the better, the longer the shelf life of its
contents, but the container sealing performance is good or bad is a prerequis
ite for achieving its barrier properties, only container having good sealing pro
perties play to ensure the efficacy of the barrier material. No matter how the
bottle cap of each barrier properties, the bottle body and the connection, i.e.
the connection cap bottle screw cap and the container is the most likely loc
ation of the leak, the position of the detection range belong cap seal perfor

2. mance, So basically sealing cap to reflect the sealing performance of the cont
ainer, one of the caps will review the project. Cap seal performance testing re
lated to national standards testing standards in the cap in the sealing cap ha
s a clear performance testing requirements. Depending on the purpose of the
cap, and the cap on non-gas measuring method gas cap have different requ
irements. Free gas cap caps need to cut anti-theft ring (bar) for not less than
the rated torque 1.2NM sealed with a seal tester, pressurized to 200kPa, kee
p up the pressure in the water for 1 minute, observe whether the leak or gas
release; gas cap is pressurized to 690kPa, keep up the pressure in the water
for 1 minute, observe whether the leak, then the pressure is increased to 12
07kPa, keep up the pressure for 1 minute, observe whether the cap release. I
n the national standards in testing, we can see the cap sealing performance
under certain of the bottle cap torque force. We are here simply to say abou
t the relationship between force and torque bottle cap sealing performance.
Cap torque force the main factor affecting the sealing performance of the tor
que is too great for opening and locking caps a great deal of difficulty, reduc
e ease of use, and the torque force is too small will reduce the container sea
led performance, which may lead to leaks in the products appear in transit.
Today, packaging design to provide more convenience for the rapid consumpt
ion, and the realization of easy-open bottle cap is one of them to achieve th
e goal. However, in the reasonable control of the bottle easy to open at the

3. same time we must pay attention to detect closely related sealing performanc
e, otherwise the situation will lead to insufficient torque force leaked lay hidd
en. Visible, sealing cap is easy to achieve container consumption detection ke
y indicators. Cap sealing performance of the detection step 1. In accordance
with GB / T17876-1999 standards of rated torque the cap sealing the contain
er finish, anti-theft ring have to be removed beforehand. Preferably with locki
ng force detection cap torque tester. 2. Prepare the sample, the sample is the
n good preparation is mounted on the test will be installed in Annex 3. Anne
x good sample to test fixed in plastic anti-theft caps sealing performance test
apparatus. Seal Tester has a sample holder can be easily fixed firmly fix the
sample in the experimental apparatus, to avoid erratic movement of the press
ing force in the process.
