The most important thing about barrier and shelf life is the fact that products spoil, but you don’t want them to. Products need to be protected from oxygen, moisture and in some cases light. How, what, where, and why? Read all about it here!

 

About barrier and shelf life

One of the most common statements is that the barrier doesn’t need to be too high. The higher the barrier, the higher the costs will become. Naturally, products with a long shelf life, don’t need a high barrier. That is why the barrier needs to fit the product. Products which need a high level of barrier, are fruit for example. Barriers are lower with products such as candy or nuts. They can last very long without being protected. 

 

Frustrations around barrier and shelf life?

When it comes to barrier and shelf life, packaging companies cope with lots of frustrations and questions, such as:

  • My barrier is too low
  • My barrier is not transparent enough
  • The run-ability of the barrier packaging is too low
  • Can we save money with lower barriers?
  • How can we improve the barrier?
  • Is my current laminate overqualified?

By choosing the producer of your packaging, these questions pop up and can provide a lot of stress, loss of money or dissatisfied clients. That is why it is so important to look for a good packaging company, which takes your frustrations and questions seriously.

 

Manufactured errors with barrier and shelf life

There are lots of manufactured errors with the topic barrier and shelf life:

  • Leaks: Leaks provide spoilage, which is bad for the barrier and shelf life. Because of leaks, moisture and oxygen will appear, which has a bad image as result. End users discover spoiled products very fast, which doesn’t increase the good name of the manufacturer or supplier at all. Some suppliers will send whole deliveries back as soon as one single product has a leak. This can cost a lot of money.
  • Barriers are to low: sometimes, the packaging of products are arranged, but when it ends up in stores, it spoils faster than expected. It is important to make a good analysis of what the barrier should be to prevent that.
  • Delamination: In some cases packaging laminates can suffer delamination. Delamination is the term for separation between laminated films after production. Of course you don’t want that, because it is bad for the shelf life and packaging stability. Delamination can have many causes, one example is the wrong use of adhesives and films. Not every adhesive fits every film or situation, which can cause this.

 

What does LPF do?

LPF helps customers when their suppliers advise them higher barriers than necessary and when they pay too much for it. LPF looks closely at the client and customer, and advises the barrier with fits the most: customization! Big suppliers generally offer more uniform possibilities. That is why clients end up with barriers which don’t fit their product requirements. LPF offers tailored solutions and will never let that happen.

Due to our tremendous amount of experience processing laminates, we can make high barriers without losing transparency or quality. Besides that, we guarantee that our products have a perfect seal strength (the force needed to open a lidding from a packaging). When this is too high clients and especially end users, would be dissatisfied because it is not practical in usage and start complaining, which is never good. When it is too low, you run the risk of your product opening prematurely.

Even the smallest amount of oxygen in the packaging can disturb the preserving of the packaging. Our technologists monitor the products all the time. We make samples of every order and make sure the order is approved, before we will send it to our clients.
