SFT eliminates the well-known problem of bags being often tough to open. Even in thin, economy, single-use bags---e.g. laundry, trash, carry, produce, sandwich, freezer, leaf, utility---in short, any flat sidewelded bag or any side-gusseted bag.

"Opens first time, every time"™ can now be offered in economy bags, the biggest market segment.

Licensing available for qualified manufacturers, marketers, retailers, supermarkets, and corporate users.

Manufacturers, distributors, retailers: GROW your business by flipping an industry-wide problem into your opportunity

In any established market, the only realistic growth potential is through customer preference. The plastic bag business is no different. Customer movement follows a better product.

SFT's technology (U.S. Patent 7,223,016) can improve and differentiate your bag products over those of your competition. It solves the well-known problem of bags being hard to open.

Manufacturers can improve their products, and let the market see the potential to save labour costs, reduce waste, and improve hygiene. This implies a migration of customers to Licensees. A limitation on the number of Licenses means some companies will lose market share to others.

The problem of bags being hard to open is industry-wide. The problem of interlayer cling is however a part of the nature of thermoplastics. It cannot be completely eliminated without losing other key properties. Managing interlayer cling adds quality-control (QC) expense, and even if your QC is excellent, there will usually be variability in ease of opening. That variability generates complaints because customers always want the good end of the variability.

If some of your bags are hard to open, this is not a problem with your QC, it is in the nature of a thermoplastic to have some degree of cling.

SFT however has a devastatingly elegant patented solution that shifts the problem from "managing cling" at the manufacture stage to "overcoming cling" at the user stage. SFT's solution is mechanical, simple, efficient, and economical. It is illustrated in the examples on this site. It has already been used in Norway and the far East.
     This can liberate QC resources, can increase tolerance for off-standard manufacturing and storage, and increase buyer appeal because it gives users a bag that will open "first time, every time". That is a powerful way to differentiate your products in the market.

The problem of interlayer cling, causing difficulty in opening bags, resonates with virtually all users. That means a receptive market is waiting to hear about your new products that will eliminate a headache that users typically thought was unavoidable in an economy bag.

The new bags open readily and reliably---one light outward tug at the edges, and it's open.

Because this is a patented technology (U.S. patent 7,223,016, pending elsewhere, and other filings), only Licensees can use it; so a License can tilt the playing field in your favour (as a Licensee).

This Licensable technology can improve and differentiate your bag products, so you gain market advantage.

License the solution, from ...

SNAP Film Technologies (SFT) owns patent and trademark intellectual property (IP) that eliminates the "hard-to-open" problem in common plastic bags. We do not sell bags, thus our focus is on helping our Licensees do well. Read about our Licensing system here.

Our core patents were approved (2007) in the EU, USA, and elsewhere.

SFT Licenses this IP to manufacturers. We can also License suppliers and major users such as retail chains or corporations or governments, etc., so they can commission the improved products either for in-house use or for further sale.

compatible with existing machinery and materials

SFT's IP is compatible with standard machinery and materials, and the improved bags come at virtually zero incremental cost of manufacture. For example, to switch a line making conventional side-gusseted bags to making Zbags™, the change is a simple adjustment that can be made even while the machine is running. The Xbags™, made in a side-weld process, require only punches to be added.

applications, products, kinds of bags:

Most conventional bags fall into one of two types: side-gusseted and side-welded. Both are improved by (respectively) our Zbag™ group and Xbag™group.

The IP brings reliable-ease-of-use™ to a wide range of applications of simple plastic bags --- e.g. bags for produce, carry/shopping, utility, bakery, sandwich, bin liner, trash/laundry, diaper, mini-cleanup/doggie-doo---in short, virtually any side-gusseted or side-welded bag you can think of.

We also have an AUTOpack group suitable for machine handling, for which we are seeking machinery partners.

BENEFITS

benefit to users and customers

The improvement directly results in savings of time/wages, elimination of waste of bags discarded in frustration, and smoother workflow.

Hygiene is improved because users no longer need to spit on fingers, or remove protective handwear, to open bags. Especially relevant to food, health, and tourism sectors.

benefit to manufacturers and suppliers

These bags are a way to gain market share. The benefit to users and customers creates a market advantage for Licensed manufacturers and suppliers.

As customers discover these bags, we expect a market shift whereby Licensees will take a large part of the market away from non-Licensees.

How SNAP™ bags work

All SNAP!™ bags operate on the same, easy, quick, 'grip and snap' method: grip the grasping points, and tug lightly -- it's a "snap": the bag opens because the back and front are pulled against each other and the cling lets go (no need to tug hard ... a small easy motion will do it). If it doesn't open, you have the wrong end.

... Physics of why they work

Most people grab the top of the bag and squish. It is an empirical approach; we don't think about it, we just do it. Why should it work at all? By squishing, we are really trying to slide one panel against the other. If it slips, a bulge or small beginning opening is formed. The problem is, however, that the squishing action also presses the panels together. It increases what physicists call 'the Normal force' that multiplies friction, making it harder to slip. Often, if the fingers are dry, the fingers will just keep slipping.

SFT's architectural approach creates the slipping action without increasing the normal force. SFT simply puts "grasping points" where you can grip each panel independently of the other. It works like a charm because it doesn't waste energy by increasing the normal force.

SFT takes a problem that used to be a pain in the neck for quality control and puts it instead in the realm of structure---puts the solution right into the hands of the user.
