Easy to Open Flexible Packagings

1) Candle flame seal. The old way of sealing polyethylene and polypropylene bags. Bag opening is folded and swipe gently in flame. The plastic melts thus sealing the bag. It produces an irregular seal making it easy to open.  Seals made by electric heat sealers are harder to open.

2) Bite it. PP and PE bags sealed with an electric heat sealer are opened by means of “bite it method”. Just bite it in absence of scissors and knife. Why bother get those sharps if own teeth comes in handy.

3) Easy pull apart seals. Common on cheaper crackers (one to two pesos each). The seal is about half inch wide and seems very strong. However, it can be pulled apart easily by hand.

4) Tear here. A “tear here” mark is printed somewhere on label, commonly on top corner. It is accompanied by a thin shallow v-shape cut. Pull it to open.

5) Zig zag end. Automatic form-pack-seal machine cut each portion either straight or zig zag. The latter looks better than the first. Seems an intentional decoration but it’s not. It is meant for easy opening. It is like a group of many “tear here”.

6) Punch here. I mean insert straw here. Seen on juices in aluminum pouches. A small hole covered with soft plastic film is provided for easy straw insertion. However, the pouch is usually turned up side down and the hard plastic straw is punch on bottom cover.

6) Screw cap. An enhancement of aluminum pouches. A screw cap mechanisms is installed on upper top corner. Unscrew to open and get contents. Screw the cap back to reseal and store the unconsumed product.

7) Thin laminates. The instant coffee in stick packages. Upper portion is thin and weak, in can be teared easily with bare hands.

8) Bread twisting ties and clips. A soft bread package is either 1) both ends are knotted, 2) tied with plastic insulated piece of wire, the same material used to organize electric cords, and 3) fixed with a bread tag or clip.
