There are many ways a heat seal liner can add value to your product and its packaging, but knowing when and how to use them is often more than half the battle. In this, the next in our closure liners series, we have some heat seal liner advice so you can have the best advantage.
Is a Heat Seal Liner Right For Your Product?
Many closure liners offer a tamper evident vacuum seal to preserve contents and demonstrate product integrity, along with a design that prevents leakage, but a heat seal liner has more versatility. Heat seal liners are best suited for packaging products that require a moisture barrier, an oxygen barrier, printing on the liner, anti-counterfeiting measures or venting.
Although they are not a good match for oils, a heat seal liner can be a perfect fit for bottles or jars filled with any of these common products:
- Fruit juices
- Glass cleaner
- Dry products
If this type of closure component is right for your product, you can then opt for a one piece liner or a two piece liner. A one piece liner would be used for a single-use product or dry product while a two piece liner would be used if there is liquid inside or if the package will be resealed. In the latter circumstance, this makes the two piece liner great for multi-serving containers.
Apart from the seal itself, you will need to make sure you have a compatible type of plastic for your product's bottle or jar. Some liners generally work with a certain type of plastic, but not all types of plastic. This underscores how important it can be to have help in managing potential pitfalls.
