Product Information

Some " polythene bags" come with their own closure method. This can be a "press-together" gripper (like our " Self Seal Again bags") or self-adhesive tape on a flap. The most common form of closure though, is heat-sealing. This is where a hot wire is pressed onto the top of the bag to weld it together along a thin line. For widths up to 400mm there are very inexpensive machines that do this very effectively and are only hot during the actual welding cycle. You can use this link to view our range of heat sealers. Printed polythene bags Firstly, remember that most polythene is much stronger than you think, and most users choose a heavier bag than they really need. But here is a guide to the duties: Apealing clear crisp, glossy quality resealable bags (all with flaps and resealable strips) made from 30 micron polypropylene (also referred to as cello). Designed for greetings cards, notecards, invitations, photos and similar flat gifts

An L-velopeis sealed on 2 adjacent edges forming an ‘L’ shaped Seal, leaving one long and one short open. You also need to be careful storing some older photographs with a gelatin emulsion. The emulsion can bond to polyester, in this case you are better to use an archival paper enclosure, or interleave with acid-free tissue.Keepsafe Envelope Extra Strong Polythene Opaque C3 W335xH430mm Peel & Seal KSV-MO4 [Box 100] 403... If you don’t want to heat seal your bags, we sell a variety of resealable bags too, ranging from coloured bags to clear bags with write on panels including a heavy duty range.

For smaller bags the minimum quantities get much higher. For multiple colours the minimums also get higher. With crystal clear quality, anti-static and PH neutral formula, our resealable artwork and photo bags help present and protect your artwork and can be used for archiving products for long periods of time. They are also durable enough to protect your photos and artworks from oils from hands and clothing whilst on the shelf. Each of these forms of enclosure have benefits which drive their suitability for items to be stored within. Consideration should be made as to how often, if ever, the contents will need to be removed, or viewed. As a general guide: Keepsafe Envelope Extra Strong Polythene Opaque DX W440xH320mm Peel & Seal KSV-MO3 [Box 100] 410...SIZING: Please note that measurements can vary by SEVERAL millimetres due to manufacturing 5% tolerances, please ensure that you have extra "wiggle-room" in the bag when your card and envelope is inserted. We recommend at least 5mm extra space should be considered. Also remember your cards and envelopes also have a 5% manufacturing tolerance and can also vary in size by a few millimetres. If the bag is too tight it could split. Once you have cut the material to your dimensions, seal with a double sided polyester tape, j-lar polyester tape or weld with a polyester welding/sealing machine. For securing fragments or irregular shapes within a clear polyester enclosure consider using a polyester spot welder. The polythene film extrusion process is complex and affected by external conditions like heat, therefore factories are unable to guarantee the size of bags exactly, and a degree of manufacturing tolerance is required on every polythene product. It should be noted that our measurements are the internal dimensions. Heavy duty bags are less conforming and, as such, are very unlikely to represent the same suffocation risk. As part of our range we do offer some self-seal clothing bags which are both perforated and printed with a standard warning notice. The link below will take you straight to them. We are aware that some 'polyester' products available on the market are not 100% polyester but are actually coated with other materials to make them easier to weld, or to print upon. This is not something we offer, beware cheaper alternatives for this reason.
