This gives the approximate amount in inches.For example, 75cm divided by 2.5 equals 30 inches.Take the inch measurement (use 0.5 for half an inch if necessary) and multiply by 2.5. Then take the length measurement and do the same, to calculate the length measurement of the mailer bag.We then match both these measurements to the nearest mailer bag measurements available, only using sizes larger to allow for movement room, otherwise it will be difficult to insert your item.For example, a product measuring 50cm around the circumference in the middle of the shortest side, and measuring 80cm around the circumference in the middle of longest side, will fit a 25cm x 40cm mailing bag (or 10x16inch), which we then recommend that the measurements are rounded up to the nearest size available on both dimensions to ensure some movement room, so in this case, would be the 300x400cm grey mailer bag ( 12x16inch Mailer Bag).Measuring the mailing bags itself to find out what size to re-order is very simple.Measure the width from side to side (that will be the width of the mailing bag) and then measure the length from top to bottom, but not including the additional flap piece for sealing the mailing bag, as this is only included on one side, and not included in the sizes stated on our website, and referred to as the lip measurement, usually around 5cm (2inches).Take the cm measurement and divide by 2.5. They feature a self-seal adhesive closure that will not re-open once closed and Measuring to find out which poly mailing bag to order to fit your item(s) is easier than first meets the eye.Simply measure the diameter of the width of the product (or products put together), by placing a tape measure under the item being packaged, and bringing the measure to top around the centre from side to side, draw the measure together and make a note of this measurement.Then do the same for the length of the product.Take the width measurement and divide by 2, this will provide the width measurement of the mailing bag. All our poly shipping bags are made in puncture- and tear-resistant 2.5 mil thickness to protect the contents.

We look forward to being of assistance. Most poly mailer packaging bags have a single sealing strip with a permanent glue, so once this seal is used to send goods initially, then it will slightly damage the grey mailer by tearing the plastic when the bag is pulled open.However, when using the grey poly mailer bag again (say to return unwanted items on a courier) if the bag is cut carefully open, then usually there is plenty of bag left to wrap around goods and this can then be resealed together with packaging tape.On the other hand, e commerce mailing bags often have a double sealing strip giving two permanent sealing strips, one that the sender uses to seal the package, and a second for the buyer to use when returning goods.These custom mailers are usually printed with e-commerce shop details and a вЂcut along the dotted lineвЂ™ text to ensure the buyer opens the bag in the correct place and doesnвЂ™t damage the second sealing strip for returning the goods.For e-commerce business, it is important to ensure staff packaging goods are correctly advised to use the most outer sealing strip when packaging goods for resale, as using the inner (second strip) does result in the outer strip not being able to be used.If bespoke printed mailers or mailing bags with double sealing strips are needed, you have further questions, or are not sure which product will work best for you, then please reach out to our friendly advisors, either on the chat box online, by emailing or telephoning 01702 205 999.
