Can cosmetic bottles be recycled?


Cosmetic bottles usually made of glass, PP plastic, or PET plastic can be recycled after washing.


In addition, some businesses also hold activities to exchange empty bottles for skincare products, such as Origin Earth Day. Empty bottles can be exchanged for gifts or decorated by oneself, making DIY a useful gadget in daily life.

Our skincare bottles are usually packaged with several materials, such as glass, metal, plastic, etc., and it is impossible to open the bottles with bare hands. Due to the complexity of the packaging materials and content, it is often difficult to recycle, and it may be buried in landfills along with other garbage or dumped into the ocean.


There are many types of plastic products, most of which are high polymers. Some can be recycled and reused, while others have no recycling value. The basic destination is incineration and landfill.

The physical recycling method for PET plastic bottles is relatively simple, mainly drying and granulating the cleaned PET plastic bottle waste. Firstly, the waste PET plastic bottles are cut into pieces, and HDPE, aluminum, paper, adhesive are separated from PET. PET fragments are washed, dried, and granulation is carried out; Secondly, first, non PET bottle caps, seats, labels, and other impurities on waste PET plastic bottles are separated by mechanical methods, and then washed, crushed, and granulated. The recycled PET must not contain PVC impurities, otherwise it will affect the color of the PET.

How do we produce plastic cosmetic bottles?


Everyone must be curious, how do we usually produce makeup bottles? Let me tell you how to do it!


Firstly, plastic materials are made into preforms and then blown. Currently, environmentally friendly plastics are commonly used in PET.

  1. Preheating is achieved by irradiating the preform with a high-temperature lamp to soften and soften the main parts of the preform. In order to maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a certain cooling device is required for cooling.


2. Blow molded bottle molding


At this stage, the preheated preform is placed in the prepared mold and inflated to blow the preform into the required bottle.

The bottle blowing machines on the market are generally divided into fully automatic and semi-automatic. By combining robot operation with two bottle blowing operations, automatic blow molding machines eliminate the need to manually put preheated preforms into molds, greatly accelerating productivity, and of course, the price is higher than semi-automatic.
