The three influencing factors of pets feeding syringe are barrier properties, sealing methods, and density of feeders. These points will have a certain impact on the sealing effect of the pets feeding syringe.
1. Barrier performance of pet feeding syringe:
The barrier criteria are mainly the O2 transmittance and the water vapor transmission rate of the material. The barrier properties of the substrate will directly affect the quality of the drug during the shelf life, and it is also an important indicator for assessing the shelf life of the drug.
2. Sealing method
There are three main types of sealing methods:
The first is to seal the outer thread of the bottle with the inner thread of the bottle cap;
The second is to use the flat pressure seal, with the capping of the bottle cap, the surface of the bottle mouth and the inside of the bottle cap The gasket is contacted to achieve the sealing;
The third is the cap sealing. During the capping process, the cap with the inverted cone or the elliptical body plug is pressed into the interior of the bottle mouth, relying on the interference between the inner plug and the inner diameter of the bottle mouth. Cooperate to achieve sealing. Which sealing method is used depends mainly on the nature of the contents of the bottle.
3. The density of the pets feeding syringe
The density of pet feeders is closely related to their barrier properties and mechanical properties, and is an important basic parameter affecting the physical properties of materials. By comparing the test results of three common substrates of PP, HDPE and PET, the density of all three substrates is within the national standard.
