With the continuous development of Syringe Blister Packaging Machine, syringe packaging tends to be more large-scale and professional. Syringe packaging is favored by users for its good quality and fast and efficient use efficiency.
There are many types of syringe packaging on the market, and the product quality is uneven. How to judge the quality of syringe products? First of all, from the appearance of the syringe packaging, the main detection methods are as follows:
The appearance inspection of the syringe package mainly includes the overall shape of the bottle body, surface color, gloss, appearance quality and other quality characteristics that are perceived by human vision. The basis of appearance quality inspection is based on the different defects of various parts of the plastic bottle, and different standards for appearance defects are formulated. The appearance quality of the syringe is usually marked with the physical object to allow the minimum allowable limit or to make a standard sample. The standard sample is best to seal one for each defect for comparison and verification. However, from the overall requirements of the syringe, the appearance quality should have a uniform milky white color, no obvious color difference, the product surface should be smooth and smooth, no deformation and obvious scratches, trachoma, oil stains, air bubbles, The push rod and the sleeve have a good cooperation.
Pre-filled syringe components are composed of needle tubes, caps, push rods or pistons. Each plastic component is produced by injection molding.
The appearance requirements of pre-filled syringes are as follows:
Needle tube: The head should be flat, free of burrs, no bends, no cracks, and no gag defects. The inner wall of the tube body is smooth and smooth without color difference.
Cap: full molding, uniform color, no cracks and deformation.
Push rod: full molding, uniform color and no deformation.
Piston: full molding, no flash, no obvious shrinkage. Plastic syringe characteristics requirements: tightness: there should be no leakage at the seal of the tube cap and the seal of the piston
Lubricity: The push rod piston should move smoothly without sudden stop.
Residue on ignition:Must not exceed 0.1% (Remaining residue on bottles containing sunscreen must not exceed 3.0%)
PH change value: the difference between the two does not exceed 1.0
Heavy metals: must not exceed one part per million
Easy oxide: no more than 1.5ml
Non-volatile matter: no more than 12.0mg
Decolorization experiment: Not deeper than the blank solution
Residue of ethylene oxide: ≤1 µg / ml
Sterile: should be sterile
