Glass jars and bottles are used to store a variety of consumer goods. When deciding on label materials, take into account where the product will be stored and how it will be used. Labels made from certain materials can be susceptible to moisture, heat, oil, and other factors. With that in mind, look for the following characteristics in a glass bottle or jar label:
Beverages sold in glass bottles will often be exposed to condensation. Chilling beer or wine in ice buckets will make them even wetter. Since you want your bottled beverages to always look their best, their labels must therefore be moisture-resistant. Labels that turn soggy, peel off, or discolor send a negative message about your brand.
Low pH or High Acid Resistant
Ketchup and other acidic condiments are often sold in glass jars or bottles. Some types of labels will degrade faster when exposed to such substances, so you want to choose a label that won’t deteriorate so easily because of that.
Candle jars are normally subjected to high heat for extended periods. You don’t want your consumers to see the candle label become brown or peel after repeated use. Selecting a temperature-resistant label ensures that your candle jars will remain pleasant to behold for a long time.
Essential oils and cosmetics may easily drip or spill over onto the exterior of their glass containers. Label types like unlaminated paper readily absorb oils and consequently discolor. Labels that are laminated or are made of polyester or other synthetic materials don’t have this drawback. They’ll continue to look good and stick well onto the bottle despite being smeared with oil.
Resistant to UV light
Bottled goods that are kept and used outside will be exposed to sunlight. UV light causes many label types to crack and peel quickly, so you must choose a label that is protected against UV radiation.
Best Label Types for Glass Jars and Bottles
There are five primary label materials that manufacturers utilize for items packaged in jars and bottles.
Thanks to its flexibility, vinyl is an excellent option for glass containers that are unevenly shaped or have small radii. Its high heat resistance makes it a great choice for candles, while its high resistance to moisture, oils, and high acid foods make it ideal for labeling wines, beers, essential oils, cosmetics, and sour condiments.
2. Biaxially-Oriented Polypropylene or BOPP
BOPP is a popular label material because it is remarkably strong and can be stretched thin. Its resistance to water, oils, and acid makes it a great choice for food and beverage items, most especially for acidic condiments like barbeque sauce, mustard, ketchup, and sauerkraut.
Polypropylene labels are less expensive than vinyl ones and are just as long-lasting, making them a great alternative for the latter. Polypropylene labels have excellent resistance to moisture, oils, and lubricants. However, because polypropylene can’t withstand high temperatures, it’s not ideal for candle labeling.
4. Polyester or PET
PET is a long-lasting label material. It resists moisture, oil, and other liquids, and can withstand temperatures up to 300°F. Because of these properties, polyester is an excellent choice for candle labels.
Paper’s broad color and tactile options are difficult to match. Paper is ideal for glass bottles and jars, but you’ll need laminated paper if you assume your product will come into contact with water, oil, or other liquids. Even then, laminated paper can’t compare to the durability of the other labeling materials discussed earlier.
Choose Your Glass Jar and Bottle Label Materials Wisely
You’ll be certain that your jarred and bottled goods will stay beautiful if you pick the right label materials for them — and the right bottle labeling machines to apply them with. Talk to your trusted machine vendor to learn more about your options.
