Concentrate Glass Jar VS Press-and-Blow Molding Glass Jar?

Here we bring you two kinds of cylinder glass cosmetic jars, in addition to the different sizes, do you find any other differences? From the style, they look very similar, while the structure and manufacturing process is different.

Different structure

The concentrate glass jar container, also called as pressed glass jars, if we observe carefully we will find the inner wall of the jar is straight up and down, there is no curved part on the inner neck part, but you can find there is a stage inside the mouth of press-and-blow molding glass jar.

Different manufacturing process

• Pressing glass container, is to install a mold and a punch on the glass forming machine, inject the liquid glass into the mold and press the liquid glass by using the punch to make the glass into the shape required by the mold.
• Blown glass container, which is made by Press & Blow Process. It can be blown into a glass container with a jar/bottle diameter larger than the mouth diameter.  

In simple terms, the glass cosmetic jars with stage inside are blown glass jars, and those jars with straight inner wall (from the mouth till the base) are concentrate glass jar containers (or pressed glass jars).

The shape of this two styles of glass cosmetic container can be round, square or other customized shapes. Usually the concentrate glass jars are used as primary glass packaging solutions for wax, cannabis concentrates, lip balm, eye cream, eye liner gel etc. And the blown glass container are ideal packaging for cream, moisturizer, gel mask, body scrub etc.
