Hardly any packaging aspect has such inexpensive features and impact to such an extent on the customer. There is a small hole in the side seal that allows a shopper to open a bag in a clean and well-organized manner, without using scissors or struggling with it. A Tear Notch Pouch is a blend of that convenience and the power and protective barriers of a new laminated film. The global flexible packaging market is estimated at about $270 billion and analysts project that this market will grow at about 4 to 5 percent annually through the year 2030 and easy-open attributes contribute towards this growth.
What Is a Tear Notch Pouch?
The name reflects a bag that has a small opening in the form of a V or short straight cut in the side seal at the top. The cut provides a starting point to the film, and thus a customer can pinch the bag and tear it across the top in a single motion.
The feature is added by manufacturers to a variety of bag styles such as stand-up, flat and gusseted styles. The notch is inexpensive since the converter punches or scores it when making the bag and it does not introduce any additional material.
How Does a Tear Notch Work?
The majority of barrier films are designed to be resistant to tearing. PET bags are made strong by layers of PET, aluminum foil, and polyethylene, which also complicate the opening of the bags. The notch forms a stress point that focuses the force at a single point and the film then tears along a straight line.
Other converters go ahead and mark a line of laser across the bag. The laser is used to cut the outer layer down a specified path and directs the tear such that it remains flat rather than flowing along the front panel.
Why Do Shoppers Care About Easy Opening?
The anger of difficult-to-open packages becomes widespread. Regular consumer surveys state that approximately 70 percent of consumers have had trouble opening a package at home and the elderly report the greatest difficulty. The first encounter with a product is enhanced by a clean tear and first impressions determine repeat purchase.
Safety is also influenced by opening. Individuals who are unable to tear a bag will tend to use knives or scissors thus spilling and occasionally injuring themselves. Any notch takes away such a risk.
Which Products Use Tear Notch Pouch & Bags?
Snack-sized goods are the most common type of product that is dry. Notched bags are used in jerky, trail mix, granola, candy and dried fruit since they are frequently opened by the consumer during the purchase. Tear Notch Pouch and bags are also found in pet treats, spice blends, powdered beverage mixes and single-serving nutrition.
The feature is used by non-food brands. Bath salts, seeds, craft supplies, and supplements are all products that have a convenient initial opening, particularly when the bag comes with a resealable zipper.
How Do Notches Pair With Zippers?
Notch placement is typically in the position of the top seal and just over the zipper used by designers. Consumers cut the upper strip and the zipper remains to be used again. When the notch is too low, the tear will cut through the zipper track, and the reseal will be destroyed.
Most bag sizes would work with a distance of approximately 10 to 15 millimeters between the notch and the zipper. Companies that pilot their layouts on actual customers tend to discover issues with placement in time to manufacture.
What Does Custom Mylar Pouch Add?
Mylar is a type of film that is covered with metal or has a foil layer. This type of film stops light, oxygen and water from getting in. Many products like coffee items related to cannabis, vitamins and foods that last a time use this kind of protection to keep the inside fresh. Custom mylar bags can let through than 0.5 cubic centimeters of oxygen every day. This can help keep goods fresh for several months or even longer.
Barrier films are not as easy to tear as polyethylene. Because of this it is more important to have a notch, on these bags. In the absence of one, customers tend to tear the bag at some angle and spill product.
Should Brands Order a Custom Tear Notch Pouch?
Simple launches work well with sizes but most companies need exact measurements. A custom Tear Notch Pouch allows a business to match the width and height of the bag with the amount of product choose where the notch goes and decide on the film type. Bags that are the size get rid of extra film and reduce air in the package.
Traditional printing requires least 5,000 to 10,000 units, for printed custom orders. Digital printing brings that number down to a few hundred units, which helps small companies test designs before making a big run.
Does the Notch Weaken the Package?
A properly crafted notch does not destroy the protection of the products. The slice is made on the outside seal, not in the sealed section containing the contents, and thus does not disrupt the barrier layers. Seal strength is measured by converters and a good notch will leave at least 5 millimeters of intact seal between the cut and the product chamber.
The actual risk is due to poor placement. A notch that is too near to the fill area may begin a leak during shipping, and as such, brands must request drop and seal-strength test results prior to approving production.
What Should Buyers Check Before They Order?
The tear notch pouch packaging entails a number of choices and a quick checklist can be used:
Movie format and protection requirements to the film.
Notch shape, depth and zipper distance.
Bag size and style of gussets.
Print method and minimum order quantity.
Recyclability, mono-material films are recyclable which is an advantage over multilayer laminates.
In the world, less than 10 percent of flexible plastic film is recovered by recyclers, and thus, material choice should be considered. Store drop-off bins accepting plastic films are now operated by many grocery chains, and brands are advised to look at local regulations before they include a claim of recycling.
Final Thoughts
A minor slice alters the customer experience with a product. The combination of the notch, film and zipper keeps the product safe makes opening easier and reduces frustration at home. Buyers who understand how the notch, film and zipper work together can ask for packaging that's kind to the product and kind, to the person who opens it.
