Pure Materials, Recyclable Containers
All glass products by Glasslock are made of silica, soda ash, limestone and other natural components, making it eco-friendly and recyclable.
Glasslock products are all BPA free and do not contain any harmful environmental hormones, neither in the glass, lids nor silicone.
Concerned about environmental issues, Glasslock chose an eco-oriented production process
since manufacturing soda-lime glass emits less carbon dioxide and consumes less energy compared to the production of other types of glass.
Glasslock delivers the flexibility of using the containers in the fridge, freezer, dishwasher, and depending on the references also in the microwave and in the oven.
Odor-free, stain-proof, it is also easy to clean and the glass will remain shinny for a long time.
Airtight and leak proof
The majority of Glasslock containers are designed to be perfectly airtight and leak proof. No bad smell nor leaks in your refrigerator anymore!
Thanks to the glass container and the airtight sealing, Glasslock storages preserve your food from oxidation and thus, keep your food fresh and crispy a longer time.
Tempered soda-lime glass
Although all Glasslock products are made of soda-lime glass, they are not all tempered. The difference between general soda-lime glass and tempered soda-lime glass
lie in the cooling process during production. The advantage of producing tempered soda-lime glass is that it reinforces the heat, scratch and shock resistance of the glass to
such an extent that the shock resistance is 3 to 5 times higher than other types of glass (from the survey “Heat resistant Food Container Verification Test report” by
the Korean Agency for Technology and Standards, June 2011). That's why it is also called "Safety Tempered Glass".
