How to Choose Best Material for Glass Jars Labels?
The best label material varies depending on the environment in which your product will be used. It’s particularly crucial to select the appropriate label material for jars that may be subjected to moisture, heat, or refrigeration.
Glass was always the best choice for food packaging and preservation because it is safe, reusable, and serves multiple functions. Glass containers, unlike plastic, do not leach unwanted chemicals into food.
When choosing a label for a Glass Jar, the following are the most important factors to consider:
Why is glass jar so good for the environment?
Glass jars are used for a wide range of purposes. Once deciding on label materials, keep the product’s environment in mind.
Resistance to Moisture
Condensation will occur in glass jar containers. They will frequently be exposed to ice to keep them chilled, which means they will be exposed to high levels of moisture. A discolored and peeling soggy paper label does not convey a positive image of your brand.
High Temperature Resistant
Candles in glass jars are a great example of commonly encountered high temperatures for a long period of time. You don’t really want your customers to start noticing that their candle label is plucking or turning brown after a couple of uses. Choosing a temperature-resistant label will guarantee that your candle glass jars look amazing from the first to the last burn.
Essential oils and cosmetics, for example, easily drip onto their containers. Specific label materials, such as unlaminated paper, absorb oils readily, starting to cause labels to turn black or discolor. Deciding on a laminated or synthetic label, such as polyester, will maintain your cosmetic and essential oil bottles looking awesome even when the product is spilled while in use.
Acid or Low-pH tolerance
Foods with a high acid content include ketchup and other condiments that are typically marketed in glass jars. Some types of labels can decay more quickly in environments with low pH and high acidity. Choose labels for your handcrafted condiment goods that won’t degrade if part of your product is spilled or dripped on them.
Products utilized outside will probably receive a lot of sunlight exposure. Certain materials are readily damaged by UV light, which causes them to peel and break. By selecting a label with UV protection, you can ensure that your glass jars continue to look beautiful even after prolonged exposure to the sun.
Think About Various Label Materials on Glass Jars
There are numerous materials that may be used to create labels, and each one has a distinct style and function that may or may not work for your business. Take a cue from some of our suggestions when selecting the type of label material:
- Standard labels are often constructed of plastic (polypropylene), have a glossy appearance, and have a permanent adhesive backing. However, these characteristics might not fit well with the design of your brand.
- Do you want your glass jars to be reusable after being used by customers? For your labels to be readily removed once the product within the glass jar has been used, perhaps a label with a detachable adhesive backing is preferable.
- Paper labels, like those on wine bottles, are available in glossy and matte finishes and are ideal for giving your goods a more hand-made appearance.
- Does your company advocate for eco- and bio-friendly actions? Labels made of hemp, recycled Kraft (for a rustic appearance! ),
The Ideal Labels for Glass Jars
Manufacturers of goods in glass jars often employ one of five major label materials. You should be aware of each of the following:
Glass jars are a good candidate for vinyl. It is flexible and adapts well to a variety of small-radius and atypically shaped containers. It is a great option for use with candles because of its strong heat resistance. Vinyl is perfect for labeling jams, marmalades, pickles, and other high-acid or low-pH foods because it is also resistant to moisture, oils, and these substances.
In particular for food and beverage items, Biaxially-Oriented Polypropylene, or BOPP, is one of the most flexible and well-liked labeling options. BOPP, a polypropylene version, is excellent for indirect contact with food since it is very resistant to water and grease. BOPP’s exceptional strength and capacity to be stretched to the limit make it special.
Polypropylene product labels are more affordable than vinyl and equally strong, making them a great substitute for some goods. Labels made of polypropylene provide excellent resistance to moisture, oils, and greases. However, polypropylene is not a good material for candle marking because it melts at high temperatures.
A long-lasting alternative for product labeling is polyester or PET. Polyester can withstand extended contact with liquids including oil, dampness, and other liquids. It can tolerate temperatures of up to 300 degrees Fahrenheit and is also very heat resistant. Polyester is a great material for candle labels for these reasons.
It’s difficult to match the variety of color and textural options provided by paper. Paper can be a wonderful option for glass jars, but if you anticipate that your product will come into contact with water, oil, or other liquids, be sure to select laminated paper. Even however, paper cannot match the level of durability offered by the other labeling materials mentioned above.
