What is poly mailers size?

The poly mailers size include length, width and flap. Generally the flap size is about 4cm-5cm for many size of poly mailers, and the flap is not influence with your product package. So you’d better calculate the poly mailer size(length and width) for your product and then give it to your manufacturer, finally they can give you an accurate quotation.

Why you should pick a suitable poly mailer size?

As I said before, the most important reason why you should pick a suitable poly mailer size is to save money. If you have too small shipping mailers that can’t pack your product, it’s basically useless. And if you’re shipping something that could be easily damaged or bruise in transit like little cosmetics for instance, you need space in there for the padding that can protect your product in transit.

Another really important thing to think about before hitting buy on your mailer order is bundling, what if your customer orders more than one product from your site? so you need a bigger mailer to handle in this case.

How to calculate the best poly mailer size ideal for your product shipping?

        1. For products that have their own box-based packaging :

Length: product length (in) + product height (in) + 2″

Width: product width (in) + product height (in) + 1/2″

Or

Length: product length (mm) + product height (mm) + 50mm”

Width: product width (mm) + product height (mm) + 15mm”

For example:

Length:210mm(8.5″) width:150mm(6″) height:40mm(1.6″)

The minimum poly mailer size is:

length: 210+40+50=300mm

width: 150+40+20=210mm

          2.  For clothes shipping

You can measure the folded clothes’ length, width and height, then calculate the poly mailers size.
