If your bike properties bottle bosses on the fork and downtube, you can attach oversised Anything or Manything Polybags, big bottles, or anything that's cylindrical in nature. On our install, we used three Anything Cages, two on the fork stuffed with rain gear and our sleeping pads and one on our downtube, holding a 1900ml Klean Kanteen Bottle, in which we either filled with water or stored additional food.

Plastic Bags Are Good for You

1% of litter? I have to say, that small stat surprises me. I don’t know how much Katherine acquires around, (on the ground, that is), nevertheless I’m a truck driver, and these plastic bags seem to be flying around everywhere. They seem to be the most normal, identifiable, type of litter I see. They may not be “clogging” our rivers, nevertheless if you take a walk next to almost any river, you’re gonna see a lot of these things stuck on branches and roots. Then there are the “bagnadoes” I see twirling above waste dumps, and yes, on the Interstate. But, let’s grant the points in the article. It still seems to me that utilising a renewable and biodegradable material is smarter than not. There are other, better, uses for ethane.

Sealable, resealable and self-sealable - there's more than one way to seal a bag

Sealable bags

Any plastic bag that can be sealed shut can be described as a sealable bag.

The sealing process can be carried out by any means, including a bag tie or clip (e.g. a sandwich bag with a twist tie), an adhesive strip, either external (e.g. sealing any bag with cellotape) or internal (e.g. as with a mailing bag), an internal self-seal strip (e.g. as with a minigrip bag) or by heat sealing with an external sealer (e.g. as with vacuum bags).

So any plastic bag that is designed with a seal can be called a sealable bag. However, not all sealable bags can be called resealable bags.

Resealable bags

Only bags where the seal can be reused can be classified as resealable bags. Some bags, such as mailing bags, feature a single-use seal that can't be reused without tearing open the bag itself and thus rendering it useless. Mailing bags are a very convenient way of sending post - thanks to their integral adhesive seal - but, because their seal is strong enough to keep the mail contents secude until the bag is cut or ripped open by the recipient, then a mailing bag is not a resealable bag, although it is a sealable bag.

Self-seal bags

Not every sealable bag be called a self-seal bag. This monicker is reserved only for bags that can be sealed closed without using any external sealing accessory - including adhesive tape, clips or bag ties - and without the use of a heat sealer to melt the polythene and seal the bag.

The most popular types of resealable bags are grip seal bags. These bags, which are sometimes known as mini-grip bags, gripper bags or grippa bags, feature an integral seal that runs along the top of the bag.

The seal contains a male (single) and female (double) ridge of plastic on opposite sides of the bag opening. When the seal is squeezed gently between thumb and forefinger, the male ridge fits snuggly into the female ridges to close the bag. This seal protects the contents of the bag from moisture, dirt and other external contaminants.

It can be used over and over again, which means the grip seal bag is a sealable bag, a self-seal bag and a resealable bag.

This handy bag is available in a huge range of sizes, made from clear, coloured or black polythene, with or without labels to make handy notes on the bag and with specialist options including antistatic bags - to keep electrical components safe - and specimen bags with accompanying record cards - perfect for hospitals, doctors' surgeries and police stations.

Methods of sealing plastic bags

The most common ways of sealing a polythene bag are by:

Sealing the bag with ties or clips. Fasten any bag shut with a plastic clip or twist shut with a tie. A popular method of sealing food bags for domestic use (e.g. clip a packet of frozen peas shut before placing in freezer, twist a sandwich bag closed for a packed lunch etc.)

Sealing the bag with a built-in adhesive flap. Some bags such as mailing bags are manufactured with a flap opening, where the flap contains a built-in adhesive strip attached along its length. Simply remove the cover from the adhesive and press the flap down to seal.

Sealing the bag with a built-in grip or zip seal. A range of bags are available with an integral strip that seals shut either by squeezing the seal together (grip seal) or pulling closed (zip seal). Very handy for regular use as they can be used over and over, these bags also provide great protection from moisture, dirt etc.

Sealing the bag with a heat sealer. If you really want to seal your bag shut tight this is the method for you. A heat sealer will bond two pieces of plastic when placed together in the sealer and the sealer is closed shut. A one-time seal, this method of sealing bags is popular for vacuum packing food.

The specimens were cured for 56 days by wrapping in a polythene suppliers film to prevent a leaching-out of ions from the cement paste, which would otherwise occur in a wet curing. Then, the specimens were dried in oven at 50C for 24 hours, ground/crushed in a mill, and then passed through a 300? µ m sieve to collect dust samples. The dust samples were diluted in 50?ml of distilled water at 50C and stirred for 5?min. Then a further 30?min of standing was applied to reach a chemical equivalent, followed by being filtered out by filter papers to acquire a solution containing chlorides then to determine the concentration of water-soluble chloride in each sample, as being regarded as complimentary one. Once complimentary chloride content was determined at a given all, the relation between complimentary and bound chloride was achieved in terms of the binding isotherm?:?the concentration of bound chloride was defined as the concentration of chlorides subtracted complimentary from the all one.

What is static electricity?

Every object in the world - ourselves included - is made of atoms, which are in turn made of protons, neutrons and electrons. While neutrons have no charge, protons are positively charged and electrons are negatively charged.

In normal circumstances, the number of protons and electrons in an atom balance each other out, meaning that atoms have no charge. However, when two items rub together or separate, the electrons contained within these items can move from atom to atom or even from item to item, thus giving the atoms a positive or negative charge.

If the items involved in this situation are made from a material that does not conduct electricity - an insulator - then this charge can not move. The result is static electricity.

How do antistatic self-seal bags work?

If any static electricity comes into contact with an antistatic self-seal bag, rather than pass through the bag and risk damaging the electrical components inside the bag, the electricity passes around the bag and dissipates before it can make contact with the components, thus removing the possibility of damage.
