Quality Guide
Over the past few years, we have received constant feedback to help develop our products and to minimise common problems that occur with mailbags.
With this in mind, we have developed six main characteristics that make a good quality mailing bag.
- Splitting Edges
A common occurrence in mail bags is the splitting edges. This can heavily interfere with the packing process.
With our mailing bags, in the sealing and cutting process of the production line, our machines use an extremely hot blade that melts the polythene film and securely seals the mailing bag in reference to its size.
With this you can be assured that your product will not fall out the bag during transit.
TO TEST: Attempt to tear the bag from the edge, gradually increasing the strength in order to test the resistance.
- Odour/Smell
A common complaint is an unpleasant odour that a mailing bag gives off, especially for people who sell clothing. Polythene is made from polymer pellets, melted to high temperature and blown; moulded in polythene film. The problem occurs with mail bags made with recycled materials that are not contaminants free, thus the unpleasant odour.
Our mail bags are aimed to reduce this unpleasant odour by using recycled material that is not contaminated. Because the bags are still melted, there is still possible chance that there may be a slight odour, but nothing that is unpleasant on the nose such as a smoky burnt smell.
TO TEST: Smell the bag internally and externally.
- Glue Stickiness
The adhesive strip on a mailbag can also be a significant issue that affects the efficiency of packaging. Some users may choose to use tape to secure parcels as they may be concerned about the security of the goods inside. However, this in turn can increase expenses with the need to use tape to pack goods.
With our mail bags we can ensure once the self-adhesive strip is peeled, sealed and settled, the bag is permanently closed and concealed; requiring the bag to be ripped in order to attain the goods. This reduces the cost of purchasing extra tape and increases the speed, efficiency and productivity. We recommend storing the bags 13-21°C for optimum performance.
TO TEST: Simply peel off the self-adhesive strip off and seal the bag. Begin to attempt opening the bag from the lip until it tears to test adhesive strength.
- Transparency
The Transparency of a mailbag can also be of concern to a supplier. If the bag is transparent, it significantly increases the risk of tampering during transit, especially for valuable products.
Our mailing bags are produced using co-extrusion technology. During the process of blowing polythene film, most suppliers compress two layers of polythene film into one; however we compress three layers of polythene film into one. This ensures the bag is 100% opaque and provides high confidentiality during transit to reduce the risk of tampering.
TO TEST: Place an item inside of the bag and flash a light on top to see whether you can see what is inside. Alternatively ask a friend to see.
- Strength and Resistance
It is important for mail bags to withstand rough handling. It is common knowledge that many courier drivers are rough when dispatching and delivering goods. This can increase chances of damaging the goods inside, or even items disappearing in transit due to easy tear mailbags.
As mentioned above, our mailbags are produced using co-extrusion technology, compressing three layers of polythene film into one layer. This results in extremely robust and durable bags, able to withstand rough handling. Furthermore, the bags are designed to be 100% moisture resistant in addition to being puncture and tear proof; additionally providing that extra security, confidentially and making the bag tamper evident.
TO TEST: Begin to tear the bag, gradually increasing the strength to test the durability and resistance of rough handling.
- Surface
There are additives put on the outer liner of polythene bags that make is easier for manufacturers to process. Due to the additives, it can leave a powder like residue on the surface of the mailbag that others may react to with redness and swelling, however this is not necessarily due to any allergies one may possess. By using the highest standard of resin, this reduces our need to use certain additives, resulting in little to no powdered residue surfaced on the mailbag. A very most important factor to consider as it can start to damage physical health. Additionally, some mailbags may feel rough, unfortunately this cannot be controlled since we are using plastic recycled resin from various sources of plastic.
TO TEST: Check whether the surface of the mailbag as smooth as it can be and glossy. Secondly, ensure there is no powdered residue on the surface of the mailbag.
