multi-layer co-extrusion infusion

multi-layer co-extrusion infusion film bag has the following advantages:
1, good temperature resistance: can be at 121 ℃ high temperature sterilization, while maintaining low precipitation after sterilization;
2, excellent clarity: good appearance of sensory, easy appearance testing;
3, a wide range of heat sealing temperature: the film has good mechanical properties;
4, high and low temperature environment flexibility: regardless of high temperature, low temperature environment can maintain good flexibility, easy to liquid emptying, packaging, storage and transportation;
Good compatibility: it can pack many kinds of drugs.

 

summarizes the relevant standards and specifications of our country and the international, and the indicators for the detection and control of infusion packaging films and bags mainly include: barrier properties, mechanical properties and so on.

1. Physical and Mechanical Properties
Physical and mechanical properties are the basic indexes to measure the protection of contents in drug packaging in production, transportation, shelf life, use and other links. Generally, they include: tensile strength and elongation, heat sealing strength, peeling strength, heat shrinkage, puncture force, puncture device retention, insertion point impermeability, injection point sealing, suspension force, aluminum-plastic combination cover opening force, impact resistance, tear resistance, rubbing resistance, etc.
(1) tensile strength and elongation: refers to the maximum stress value and elongation of the drug packaging material before breaking. The problem of packaging damage caused by insufficient tensile strength of the selected packaging material can be effectively solved by testing.
(2) heat sealing strength: also known as heat sealing strength, is the evaluation of drug packaging heat sealing part of the sealing strength of the analysis index. If the heat sealing strength is insufficient, it will cause the packaging to crack at the heat sealing place, drug leakage, pollution and other problems.
(3) Puncture force test: Used to evaluate the puncture resistance of drug packaging materials and rubber plugs.
(4) puncture instrument retention test: Used to evaluate the ability of the rubber plug to maintain the puncture device after being punctured.
(5) Insertion point impermeability and injection point sealing test: Used to evaluate the sealing of the puncture point after the rubber plug is punctured.
(6) Suspension force test: Used to evaluate the suspension resistance of infusion bags.
(7) Opening force test of aluminum-plastic composite cover:is used to test the opening force of the aluminum-plastic composite cover.
(8) Impact resistance:Prevent the occurrence of packaging surface damage due to insufficient toughness of pharmaceutical packaging materials when impacted and dropped, and effectively avoid the damage caused by impact or drop in the circulation of drugs.
(9) Tear Resistance:Drug packaging and packaging materials may be torn due to external forces during storage and transportation, and sufficient tear resistance can reduce the transmission of tearing, thereby avoiding packaging damage. In addition, tear performance is also an important indicator of whether the packaging is easy to open. The size of the tear force determines the degree of difficulty for consumers to open the packaging.
(10) Pressure resistance: In the process of storage and transportation, stacking and extrusion will inevitably occur, which will affect the packaging performance of materials. By simulating the stacking and extrusion damage of packaging in the process of storage and transportation, the changes of sample performance before and after the test are detected, and the pressure resistance of materials is scientifically analyzed and judged.
2, thickness test

whether the thickness of pharmaceutical packaging material is uniform is the basis for testing its performance. Uneven thickness of packaging materials will affect the barrier, tensile strength and other properties; high-precision control of material thickness is also an important means to ensure quality and control costs.
