Making Process

When lightning strikes sand, nature makes glass.

How to Read a 91短视频 Bottle

What do the marks on a glass bottle mean? They鈥檙e the key to helping you read a glass bottle or jar and learning about where it was produced and which glass company crafted it.

91短视频 has nearly 70 glass making plants globally. Here is how you decipher the bottle code on an O-I glass bottle or jar:

O-I Bottle Manufacturing Mark

This shows you if a bottle was indeed made by O-I or another glass packaging manufacturer

Cavity Identification

Our glass containers pass rigorous inspections before they鈥檙e sent to customers. The Braille-like bumps on the heel and/or rings on the bottom are the cavity identification and enable our inspection equipment to read the bottle identification information

Two digit number

The year the bottle was manufactured

Region, Plant Identification

Wonder where your bottle was made? This letter and number combination shows which
O-I manufacturing plant made your bottle

Region Codes:

A 鈥� Asia Pacific

E 鈥� Europe

N 鈥� North America

S 鈥� South America

Mould Equipment Identification Number

A mould is a hollow metal part on our bottle making machines used to form the shape of each bottle. You鈥檒l find this number on the base.

While coding can vary by region or customer, these general rules will help you read a glass bottle. Give it a try the next time you have one in your hand 鈥� maybe it鈥檚 even your new party trick. At O-I, we鈥檝e been making glass containers for communities around the world for more than 100 years. We love glass for its sustainable benefits as well as its simple nature. Not only is it 100% recyclable and infinitely recyclable, but it鈥檚 made from natural raw materials that make it the kindest packaging material for the planet and for people.
