Stretching in the machine direction is normally done by means of a machine direction orienter (MDO) via rolls with increasing speed. Typical products are, for example, tear stripes or polypropylene adhesive tapes.

At Lenzing Plastics we produce Cast PP films using MDO (Machine Direction Orientation) technology. This enables us to achieve unique product properties that guarantee high customer benefits and differentiation from mass-produced products.

For more than a decade, Trico Specialty Films has manufactured monoaxially-oriented polypropylene (MOPP) film in the U.S. to meet the needs of a wide range of industries. Whatever your business, challenge, or product need, we work with you to devise the best solution for your unique situation.

2 天之前 · Oriented polypropylene films must maintain their dimensional stability and barrier properties while withstanding mechanical stresses during manufacturing and use. ... preferably ≤12 μm. The film has a monoaxial orientation in machine direction of at least 1:2, preferably 1:3, and an orientation ratio in machine and transverse directions of 1 ...

MOPP是 「Monoaxially Oriented Polypropylene Film」的簡稱， 即「 單向拉伸聚丙烯薄膜 」， 通常拉伸方向為機械方向(Machine Direction)，即為薄膜的縱向。

Novel approach of applying the ternary polymer blend of long-chain branched polypropylene (LCB-PP), conventional polypropylene (PP), and hydrogenated polydicyclopentadiene (hDCPD) has been employed to tensilize biaxially oriented polypropylene (BOPP) film in the machine direction (MD) by successive sequential biaxial stretching method.

Biaxially oriented polypropylene (BOPP) film is film stretched in both machine and transverse directions, producing molecular chain orientation in two directions. BOPP film is produced by a tubular process, in which a tubular bubble is inflated, or a tenter frame process, in which a thick extruded sheet is heated to its softening point (not to ...

🔸 BOPP是「Biaxially Oriented Polypropylene」的簡稱， 即「 雙向拉伸聚丙烯薄膜 」。 🔸 「雙向」拉伸的意思是指： 縱向(Machine Direction，MD) 與 橫向 (Transverse direction,TD)拉伸。

Examples include biaxial oriented polypropylene (BOPP), biaxial oriented polyester (BOPET), and coextruded barrier films. These are oriented and then annealed to fix the orientation and prevent shrinkage.

Biaxially Oriented polypropylene (BOPP) is a type of polypropylene film stretched in the machine direction (MD) and the transverse direction (TD). This biaxial orientation process enhances the film’s properties, making it suitable for a wide range of applications and one of the most popular and highly demanded films worldwide.
