Nano Coating Machine

Nano Coating Machine

1.  150m/min high speed has already reached the international most advanced level.

2.   Rewind and unwind both adopt double position and equip with semi-automatic to connect paper device, The machine can change the rolls of base material nonstop, It will reduce the waste.

3.   When the double sides adhesive tape coat twice, it will effect the quality of products, but the technology of double sides coating meanwhile will solve the questions.

Calculation method of BOPP tape cost

Core tips:

     Commonly used specifications for sealing tape are 5.5cm, 45cm, etc. The general unit is expressed by "m" or "code" (1 yard = 0.9144m); the calculation method of the unit price of each coil is usually calculated by "yuan/square meter". The price of tape, the average merchant is reported to the customer according to the price of a roll, so simple and more clear. Sealing tape specifications:

     It is expressed by "width × length × thickness", where "width" is the width of the tape, generally expressed in mm or cm, generally ≥ 12mm, common specifications are: 5.5cm, 4.5cm, etc.; "long" is opened for the tape The total length in the future is generally expressed by "m" or "code" (1 code = 0.9144m), common lengths are 50m, 100m, 150m, 200m, etc.; thickness refers to the total thickness of BOPP original film + adhesive layer (unit: Micron, μm), commonly used 45 ~ 50μm. Such as "5cm × 100m × 50μm".

The calculation method of the unit price of each roll of tape:

     The tape industry usually uses “yuan/square meter” to calculate the price of the tape, then “price per roll = width (m) * length (m) * square price”.
The specific price has a large fluctuation according to the cost, because BOPP film and glue are all petroleum products.

     The price of BOPP precoat film is based on BOPP film thickness, EVA coating thickness, and order quantity.
Generally BOPP pre-coated film, BOPP film thickness is 12-20 microns, the thickness of the glue layer is 5-15 microns, and the glue layer is EVA.
In this way, the specific price can be calculated based on the thickness of both.

Characteristics of several coating methods -

Wire scraper
These scrapers are made of high-precision cold-drawn round steel wrapped around stainless steel wire. If the wire scraper is rotated by the micro DC motor during the scraping, the effect is better. The wire scraper usually acts directly on the substrate when the glue is applied. However, it is generally only used for the pre-squeegee coating of the smooth roll. A precise squeegee of a comma blade is usually required later.

Air squeegee
The air squeegee mechanism acts on the sizing roller by a uniformly sprayed gas (pressure) flow, which serves the purpose of squeegeeing. The gas (pressure) flow is required to be evenly distributed over the entire width of the optical roll, and this type of scraper is often used for scraping a good fluidity. The scraper has a high precision of scraping, and is currently widely used for coating scraping of whiteboard paper.
