nVs | The Sabram Scale | The Rockmuller Scale |
1 | Very loose. Probably a knocked-off product. You can see the teeth from the Saran Wrap. | No attraction or friction whatsoever, static or material. The wrapping is almost impossible to get an adequate grip on for purposes of removal. |
2 | A bit tighter than 1 but was the first dozen knocked off in the evening's printing. | Low material friction. Fingernail, compressed carbon (diamond), or other relatively hard mineral substances are capable of obtaining an adequate grip for tearing purposes. Removed material has no static attraction. |
3 | May still be either a knock off or if an obscure label, a low production quality. | Approaching normal friction and low static charge. Material is relatively easy to remove with any sharpened object, and once removed, material will raise micro-particles and fine hair as long as proximity does not exceed 0.50 - 0.75 centimetres. |
4 | You start going from opening it up with your fingernail to needing something more pointed like you keys. | Normal cellophane friction, low static charge. Material is easy to remove by any conventional method; however, after removal, micro-particle interaction extends out to 1.5 centimetres. |
5 | You can see multicoloured sheen of professional quality shrink-wrap after a long production run. | Normal cellophane friction, moderate static charge. Cellophane will actively stick to moderately charged surfaces, lightly to itself, and moderate particle interaction approaches 3 centimetres. |
6 | Quality starts to kick in and the "double wrap" is in. There is the cellophane wrapping and that multicoloured sticker keeping it closed. | Slightly above average in all respects. Material will actively stick to itself when removed, particle interaction averaging 4 - 4.5 centimetres. Noticeable 'peel' effect against organic matter. |
7 | The sticker has a record company label hologram on it. It is still perforated so you can easily open it. | Approaching limits of standard cellophane. Material sticks firmly to organic matter, raises particles from distances exceeding 5 centimetres, and is capable of forming a tight seal when stretched (Example: Kitchen plastic wrap) |
8 | They don't have the sticker perforated and you need a real knife edge to open it | Limit of natural friction and charge. Plastic is extremely difficult to remove from organic matter, adheres and forms tight seals with anything brushed against it, particle effects 6-7 centimetres. |
9 | Comes in one of those tall boxes that is also wrapped making it a "triple wrapping". You end up throwing out more material than keeping. | Material will actively attach to objects within particle range of up to 5 centimetres and form seal based on static attraction. Seal is tight enough that removal often results in tearing of material. |
10 | A time capsule item. Get the x-acto knife and watch your fingers. Very thick cellophane is used and it shows signs of pervious attempted entry by other customers. | Layer of cellophane becomes one with organic matter, inseparable by any means. Static charge is close to audible as a distinct hum. Material is classified as a dangerous substance at this point, and should be marked for immediate incineration. |
