4.0 Mail presentation
4.2 Mail sequence PremierSort Flex mail should be presented in a geographically random order.This maximizes throughput of the process and minimises risk of delay. The easiest way to make sure the mail is in random order is to stack the ‘print file’ by surname in alphabetical order. 4.3 Flexibility Items must be flexible enough to bend into an ‘S’ along their longest edge. The ‘S’ test is intended to indicate when a mail piece is too stiff to be safely handled by the automation equipment without it being damaged by the equipment or it damaging the equipment. 4.4 Non-machineable items The following are classed as non-machineable: • Polywrap, plastic or window envelopes without plastic film • Enclosed inflexible objects such as coins, pens and keys • > 5mm thick per item • Heavier than 100g per item • Metal inserts (e.g. foil or aluminium), as any detection of metal will not allow the item to be machine sorted 4.5 Paper weight • Envelopes – 70gsm minimum • Postcards – 200gsm minimum with a minimum thickness of 0.25mm
Mail must be presented in mail trays provided by Whistl. Mail must be placed in the trays un-banded, all facing in the same direction and the correct way up.Trays should not be overfilled as it makes handling difficult and can cause sticking envelopes. Each tray will need to be clearly identified with a tray label. See section 6.3 for tray labelling. In the case of letter sized envelopes the mail should be placed with the address the right way up and sitting upright.
E.g.
In the case of light large letter envelopes the mail should be placed in the same direction with the address side facing down.
Note: mail in trays cannot be double stacked.
4.1 Mailing items The customer must ensure where possible that mailing items of a similar weight, shape or size are securely placed in Whistl trays. The number of mailing items in each tray will depend on the nature of the mailing items. This will normally be determined by their size and thickness. Mailings that are presented must be separated according to format: • Letter • Light large letter • Items will also need to be separated if you require part of your mailing to have the indicia or the return address sprayed by our sortation machine
