How to solve the agglomeration of bottled powder health products?
Quality issues:
Unopened bottled powdered health care products will agglomerate during the shelf life.
Cause Analysis:
(1) Packaging materials
• Poor barrier properties-the permeation rate of external gas (such as external water vapor) into the bottle is relatively high, which can easily cause agglomeration of powdered health products. It is necessary to monitor the water vapor permeation of the bottle.
(2) Finished product packaging process
• Poor airtightness——Poor airtightness of the bottle mouth, which is prone to air leakage under a certain pressure or long-term storage, which is generally caused by the imperfect cap or seal of the bottle. For plastic bottles, it can be verified by monitoring the sealing performance (negative pressure method) test. For glass bottles or metal bottles, it can be verified by monitoring the cap opening force or torque force index to verify whether the cap opening force value is too small.
(3) Production process of health products
• The powder has high humidity-the powder has poor looseness and high moisture content, which is easy to agglomerate.
Expert advice:
——Pay attention to the main performance of the bottle, such as water vapor transmission, sealing performance (negative pressure method), opening force or torque force.
——Choose a bottle with high barrier material. Reasonably control the opening force value of the bottle cap, not too small to ensure the tightness of the bottle mouth.
——Control the drying process of the health product powder to reduce the moisture content.
What should I do if bottled health drinks are prone to leakage at the mouth of the bottle?
Quality issues:
Some bottled health drinks have leaking from the bottle mouth when they are not opened.
Cause Analysis:
——Product packaging process
• Poor airtightness-the beverage bottle mouth is prone to slow air leakage or liquid leakage under a certain pressure or long-term storage. If the cap torque is too small, air leakage or liquid leakage is likely to occur, and the bottle cap can be tested Three tests of torque force, sealing performance (negative pressure method), and pressure resistance are verified.
Expert advice:
——Pay attention to the daily monitoring of the main performance of beverage bottle cap torque, sealing performance (negative pressure method), and pressure resistance performance.
——Choose an appropriate bottle cap torque force, not only to ensure that the user is easy to open, but also to ensure a good tightness of the bottle mouth.
Why does the gas composition inside the nitrogen-filled packaging of health products change?
Quality issues:
For health products in the form of nitrogen-filled packaging, after a period of storage, the gas composition inside the packaging changes.
Cause Analysis:
(1) Packaging materials
• Poor barrier properties-poor barrier properties to the nitrogen and carbon dioxide gas filled inside the package, and air and oxygen outside the package, resulting in the loss of gas inside the package, and the gas outside the package gradually penetrates into the package, causing the gas inside the package Changes in composition.
• Poor rub resistance-for aluminum-plastic composite film or aluminized composite film, if the material has poor rub resistance, it is easy to form creases, pinholes and other problems on the packaging surface, resulting in reduced barrier properties.
(2) Finished product packaging process
• Poor airtightness-if the heat-sealing strength of the packaging bag is not suitable or there are creases, pinholes and other problems on the surface of the packaging bag, it will easily lead to poor airtightness of the packaging, air leakage, and gas components inside the packaging. Variety.
Expert advice:
——Focus on headspace gas analysis, oxygen transmission, nitrogen transmission, carbon dioxide transmission, air transmission, oxygen transmission after kneading, nitrogen transmission after kneading, carbon dioxide transmission after kneading, air transmission after kneading, heat sealing Monitoring of key performance such as strength and sealing performance (negative pressure method).
——Improve heat sealing parameters, improve the quality of existing packaging materials, and select packaging materials with high barrier properties and good rubbing resistance.
