Sakura blossom necklace and earrings with YUPO paper

I wanted to try doing something with a material rarely used in jewelry making — YUPO paper. YUPO is not actually paper, it is thin sheets of polypropylene. As such, it has some interesting properties, such as being waterproof and very difficult to tear, that normal paper doesn’t have, which suggest some intriguing possibilities. YUPO is normally used for printing, and some artists also find it a great watercolor and ink medium.

One property of YUPO that I’d read about was that it will warp when exposed to heat (so using it to make lampshades, for instance, is not very practical). I was curious how much heat was necessary and what this warping looked like, so I held a scrap piece above a candle flame to see how it behaved itself. Watching the piece of paper curl, shrivel, and thicken in the heat gave me an idea of how to take advantage of this unique feature of YUPO.

Using fabric or paper flowers in jewelry isn’t new, but both materials, while often producing realistic and beautiful results, require delicate handling, and can be completely ruined by moisture. Since YUPO is waterproof and extremely durable, this wouldn’t be a problem, and even the curvature that it acquires when exposed to heat would be completely unaffected by normal wear and handling, and, conceivably, even withstand some brief abuse from children and pets. (Please note: I’m not suggesting that either YUPO paper or jewelry made from it would make good toys for pets or children. At the very least, a sheet of plastic can present a danger of suffocation, and jewelry tends to have small parts and be a choking hazard. So please keep younger children and animals safely away.)


Use of Plastic Stretch Film for Transportation and Storage

Stretch wrap or stretch film is a highly stretchable plastic film that is wrapped around items. The flexible recovery keeps the items strongly bound. In gap, shrink wrap is applied freely around an item and shrinks strongly with heat.

It is commonly used to unitize pallet loads but also may be used for bundling smaller items.

Types of stretch film include bundling stretch film, hand stretch film, extended core stretch film, machine stretch film and static dissipative film.

    bundling film SingaporeBundling Stretch Film: Bundling stretch film can be used to fix tiny items together, and can save time and money replacing heavier and more costly wrapping products. Bundling wrap can restore the use of tape and twine to packaging tiny items together. Unlike tapes bundling wrap will not fix to the product.

hand-film-cat-iconHand Stretch Film: Hand stretch Film is used to hold items together in packaging and palleting applications. Stretch films are designed to grip firmly to objects and provide a safe overwrap to guard them from shifting during transportation.

extended-core-cat-iconExtended Core Stretch Film: Extended core stretch wrap is used to wrap pallets. The extended cores make for easy stretch film application for bundling items together or wrapping pallets.

machine-film-cat-iconMachine Stretch Film: Machine Stretch Film offers long-term load retention and high puncture resistance that you need for pallet wrap. Our machine stretch film has excellent cling and consistent machine-ability resulting in tighter and more stable loads, and its high clarity is ideal for inspection of your goods.

JPcVcrWexPMHhTwStatic Dissipative Film: Static Dissipative Film maintains all the same properties of conventional hand wraps without any of the static. Therefore, this stretch film is ideal for use in pallet wrapping products that are susceptible to static electricity, such as flammables, electronic equipment, paints and chemicals.


The most common stretch wrap material is linear low-density polyethylene or LLDPE, which is produced by copolymerization of ethylene with alpha-olefins, the most common of which are butene, hexene and octene. The use of higher alpha-olefins (hexene or octene) gives rise to enhanced stretch film characteristics, particularly in respect of elongation at break and puncture resistance. Other types of polyethylene and PVC can also be used. Many films have about 500% stretch at break but are only stretched to about 100 – 300% in use. Once stretched, the elastic recovery is used to keep the load tight.Machine Wrap

What is A4 Paper?

A4 paper is the standard paper size used worldwide, with the exception of countries. A4 paper is about 8.27 inches by 11.69 inches (21 cm by 29.7 cm). This and other types of “A” paper sizes are based on a metric measurement system and established through international European standards.

Basis for Different Sizes

A-Size-PaperA4 paper and a-like sizes are based on metric dimensions. An A0 piece of paper, when spread flat, has apart of one square meter and is the largest dimension at 84.1 cm by 118.9 cm. A0 paper, cut in half, becomes size A1 at concerning 59.4 cm by 84.1 cm. A1 cut in half is A2, and so on throughout A6.

B Size PaperThis produces paper with dissimilar sizes, but all with a 1:1.414 height-to-width part. European standards also wrap B paper sizes. B0 paper is a meter wide and 1.414 meters tall; B1 is B0 cut in semi, and so forth through B5.

The worth of this system for paper sizes is that every size is proportionately identical to the next. A4 paper, for example, is 21 cm by 29.7 cm, while A3 is 29.7 cm by 42 cm. If someone has text or images on a sheet of A4 paper and wants to increase it onto A3 paper, it can be done fairly easily without lose any of the content of the document. This amount, which uses the square root of two, or 1.414, is recognized as the Lichtenberg Ratio, named for the German physicist who initial noted its usefulness.

Size and Standardization

Paper sizes were consistent in Germany in 1922, and adopted during Europe in 1930, via Standard 216 of the International Standards Organization. The ISO is a non-governmental unit that publishes international values. While the standards have been efficient occasionally, the sizes used have been maintained since the early on 20th Century.A4 Copy Paper

Paper Weight

The mass of European paper is based on the metric scheme and is standardized under ISO Standard 536, initially developed in 1976 and updated in 1995.

What is the Paper Manufacturing Process?

The procedure of making paper dates back to ancient Egypt. This manufacturing procedure uses natural fibers and materials, liquid, and pressure to make paper. While the equipment and materials worn in the paper manufacturing procedure have varied over time, the real process remains essentially unchanged.

In the paper manufacturing procedure, organic materials such as wood or bamboo are estranged into fibers or ground into a very well powder. The reason of this step is to create uniform fibers that are then awash in an acid or base solution to make cellulose in a process called pulping. What is the Paper Manufacturing ProcessThis cellulose material is the major component of paper. In field papers, such as parchment, cloth fibers may also be used in rest of cellulose as part of the paper manufacturing procedure.

There are three methods used in the pulping method: chemical, mechanical, and de-inking. The first two processes are used to create virgin paper, while de-inking is used to make recycled paper products. Every of these pulping methods has it’s possess advantages and disadvantages in the paper manufacturing procedure.

Natural Fibers and PulpedAfter the natural fibers are pulped and twisted into cellulose materials, filler materials may be added to make special characteristics in the end product. This method is called sizing, and it can be used to make paper with a higher ink absorption rate or to alter the color of the over paper. These filler materials may comprise china clay, bleach, chalk, or additional additives.

The treated cellulose pulp is run through a drying procedure in a paper machine. This machine uses heat and pressure from rollers to take away the liquid from the pulp. As the pulp actions from the wet end to the dry end of the dispensation equipment, it is pressed to manually take away the bulk portion of the liquid. Forced heat is then used to evaporate the residual fluid, leaving dried, uncoated paper with fewer than 6% water content.

Paper Cutting MachineUncoated paper is sometimes treated with extra sizing. The paper is given a thin coating of sizing materials that aid it in accepting ink extra readily or to add an exact finish to the paper. By adding coating to the paper, lofty gloss, matte, and semi-matte property can be achieved.

The product of the paper manufacturing procedure is a single continuous piece of paper. This finished paper is collected on reels for storage space or sent to a paper cutting machine. Reels of finished paper are used in the printing trade, while cut paper is often sold for use by customers.
