What are self-seal bags?
Self-seal bags are polythene bags that are closed by squeezing an interlocking plastic seal that runs across the top of the bag. The same seal is pulled apart gently to open the bag.
This re-usable seal allows self-seal bags - also known as resealable bags, mini grip bags or grip-seal bags - to used repeatedly, avoiding leakage and providing protection from external contamination without the need for any kind of bag sealer (e.g. tape, clip, staple), thus differentiating them from standard polythene bags.
Blessed are the cheesemakers, for they shall use self-seal bags
You may have noticed more and more food producers using resealable polythene bags to package their food in recent years, in a bid to win over consumers by allowing them to keep their food fresh for longer.
Cheesemakers have been at the forefront of the move to self-seal bags, with Cathedral City among those to lead the way, but you will also find resealable bags being used from products as diverse as Bird's Eye Field Fresh Garden Peas and Cadbury's Creme Egg Splats.
Richard Clothier, managing director of cheesemaker Wyke Farms, who introduced grip-seal packs to its cheese in 2009, believes the benefits of producing resealable packs outweigh the extra costs involved in manufacturing the packaging.
"Aside from being convenient and retaining the branding throughout the life of the product, reseal prevents the use of secondary packaging in the home such as cling film and foil," Clothier told packagingnews.co.uk.
"Reseal costs the manufacturer more money, but we see it as a marketing investment in the same way that we would view investment in more flavours and better quality. It's part of the package."

BTM and MFS sampling was performed all 1 to 2 weeks throughout the surveillance period, for a all of 75 times on farm A, 59 times on farm B, and 55 times on farm C. At each sampling, five 50-ml milk sample aliquots were collected from the bulk tank through the outlet. Additionally, 1 to 2 in-line MFS samples through which the milk collected in the bulk tank had been filtered were collected into Minigrip bags. The milk sample aliquots and the MFS samples were collected by the farm staff and delivered to the laboratory within 24 h in packages containing ice packs. The samples were analysed immediately upon arrival to the laboratory. Each of the five milk sample aliquots was analysed individually nevertheless together composed one BTM sample: the BTM sample was considered negative if all five aliquots were negative, and it was considered positive if any one of the five aliquots tested positive for L. monocytogenes . The utility of MFS samples as indicatours of BTM pollution with L. monocytogenes was explored in simultaneously collected pairs of BTM and MFS samples ( n = 182). In the potential case where two MFS samples were collected with a BTM sample, such a BTM sample was paired with a positive MFS sample if either of the two MFS samples was positive, and it was paired with a negative MFS sample if both of the two MFS samples were negative.

Refering to FIG. 1 it can be seen that gripper bags 1 and 2 have flutes formed therein. These are to ensure that air is not trapped in, or excluded from the space between the gripper bags. It will be noted that more flutes are used on the gripper bags of the present invention, this ensures that they are better able to grip the wall of the duct, and are capable of greater inflation. The flutes are necessary to prevent pressure build up or form between the gripper bags when the duct motour is in operation. Such pressure effects would hinder the complimentary operation of the duct motour. It should be noted that the material used for the gripper bags, should, be flexible without being excessively elastic.
It's a WRAP - report finds self-seal bags are a winner with consumers
A March 2013 report by the Waste & Resources Action Programme (WRAP), a government-funded not-for-profit company tasked with increasing recycling and reducing waste, found that consumers are in favour of re-closable packs.
The paper, entitled 'Consumer Attitudes to Food Waste and Food Packaging', reported that consumers viewed re-closable packs as the most useful packaging innovation available to them.
Presented with 13 "recent changes to food packaging" and asked to choose up to four that "are/would be most useful", 56% of respondents chose re-sealable packaging.
The report also found that, when presented with two cheeses - one packaged in a resealable pack and the other in a non-resealable pack - two-thirds (67%) of consumers chose the resealable option. Their reasons for the choice were as follows:
- The top reason for choosing either option was a preference for how the packaging looked (18% mentioning this for the normal pack, 33% for the re-closable pack).
- Of those who chose the re-closable pack, 20% said they did so for exactly that reason (despite the fact the text was not enlarged in any way, i.e. they recognised or were looking for this functionality).
