Sealing property of bottle body and lid, water vapor permeability
Adaugat pe 17/03/2020 03:20:26 de kexonplastic

At present, most of the drugs, nutrition and health care
products, and various foods and drinks sold in the domestic market are packaged
in
plastic
bottles
. You can go to drugstores or supermarkets and
see products packaged in plastic bottles everywhere.


Plastic bottles are characterized by their light weight,
non-friable, clean and beautiful appearance. Some technical indexes and a large
number of data show that they have excellent chemical resistance and water vapor
permeability resistance sealing performance. They can completely play a role of
safety shielding and protection for the products contained within the validity
period.


Principles for selecting plastic bottles:


1. No matter what raw materials are selected for plastic
bottles, they must first meet the requirements of innocuity and no peculiar
smell. As there are many kinds of main raw materials to choose from, it is
necessary to select the comprehensive properties of raw materials. At present,
the domestic packaging bottles of nutritional health products and foods are
mainly made of PET or HPDE, while the bottle caps are made of PP.


2. Sealing property of bottle body and lid and water vapor
permeability. Sealing property and water vapor permeability are two important
technical indexes of plastic bottles, which have a crucial influence on the
stability of packaged products.


3. Plastic bottle product quality standards. The quality of
products can be analyzed and judged from the product quality standards of the
manufacturers.


4. Quality assurance system. Auditing suppliers has become an
essential part of purchasing plastic bottles. Through auditing, a comprehensive
and correct evaluation can be made on the comprehensive level of software and
hardware facilities, technical equipment and quality of the production
plant.


Ningbo KeXon Plastic Co., Ltd. is a comprehensive plastic
packaging enterprise integrating design, production, and sales.
