What industries can fin seal pouches be used in?

Generally, the food industry is a huge market.

For fin seal pouches specifically, this food market can be expanded into the dry, inflatable, confectionary, and miscellaneous foods.

Dry foods include nuts, cookies, various snacks.

Inflatable foods mainly mean chips.

Confectionary foods encompass gummies, chocolate, gum, and various hard candy.

Other types of food include noodles, teas, powder sauces, and spices.

Sometimes, fin seal pouches are also used to package toys and a lot of other products.

Another surprising application is packaging magazines, collector cards, and promotional material!

 

What are some opening designs for fin seal pouches?

There are 3 main tear notch designs: vertical, horizontal, and a pouring nozzle.

A vertical tear notch is similar to the asymmetrical seam (scroll up).

Both of them are good if your products are such that people are likely to pour them out in a bowl instead of eating right from the bag.

This works with smaller snacks.

A horizontal tear notch is similar in use to the symmetrical seam.

It is great if your products are big and likely to be eaten in one sitting right from the bag, like chips.

A pouring nozzle will have a similar effect as a vertical tear notch.

However, it is good if your products are really small, like tiny candy, powders, or even loose-leaf tea.

Basically, something that will be partitioned into small portions over time.
