It requires a minimum surface energy of 38 to 42 dynes/cm for ink adhesion, achieved through corona treatment. Flexographic printing is the ideal method, running at 150 to 400 m/min. RAZP, a trusted manufacturer of CI and stack flexo printing machines, builds presses specifically for BOPP film production. BOPP film is one of the most popular substrates used for flexo printing in large-scale labels or [flexible packaging](https://www.zp-flexopress.com/wp-content/uploads/wp-mfa-exports/page/flexible-packaging-printing-machines.md). [**What does BOPP mean in printing**](https://www.zp-flexopress.com/wp-content/uploads/wp-mfa-exports/page/label-printing-machines-video.md)**?** Understanding the **BOPP meaning** in production means selecting the right substrate, configuring the correct equipment, and avoiding costly ink adhesion failures. This article covers **what BOPP is**, how it is used in manufacturing, and in the label and packaging industry. It also discusses why flexographic printing is an ideal method that matches BOPP’s technical demands at production speed. ## What is BOPP? What is Biaxially Oriented Polypropylene? **BOPP** stands for biaxially oriented polypropylene. This substrate is used in [flexographic label printing](https://www.zp-flexopress.com/wp-content/uploads/wp-mfa-exports/taxonomy/product_cat/label-flexo-printing-machines.md), shrink sleeve production, food-safe adhesive labels, FMCG, and personal care packaging. FMCG means _Fast Moving Consumer Goods._ This plastic film is made from polypropylene resin and stretched in two perpendicular directions during manufacturing. They are stretched from the machine direction (MD) to the transverse direction (TD). This biaxial stretching process increases tensile strength, optical clarity, and barrier assistance, at a lighter weight than paper or PET alternatives. ### How is BOPP Film Manufactured? Manufacture of **BOPP film** begins by extruding polypropylene into sheets. These films are stretched either in both dimensions together or alternately in both directions to give them improved characteristics. After stretching, [corona treatment](https://www.zp-flexopress.com/wp-content/uploads/wp-mfa-exports/post/what-is-corona-pre-treatment.md) is carried out on the film to raise its surface tension above 38 dynes/cm. ### What is BOPP paper? BOPP is not paper. Rather, it is a fully synthetic plastic film. Its surface behaves differently from paper. BOPP film is applied to “paper” labels and acts as a protective wrap or as a laminating plastic. ## What Is BOPP Film Used for in the Label and Packaging Industry? ![High speed color printing on plastic film](https://www.zp-flexopress.com/wp-content/uploads/2026/05/4-5-e1779266236198-1200x655.webp) Label converters and packaging buyers choose **BOPP label** film because it survives conditions that destroy paper-based labels. Moisture, oil, acid, and rough handling do not affect **BOPP labels.** The most common applications include: - **Pressure-sensitive labels (PSL)** are self-adhesive labels for food and beverage, personal care, and household products. - **Wrap-around labels** for bottles and jars where high moisture exposure is constant. - **In-mold labels** (IML) for dairy and food containers, where BOPP integrates directly into the container wall during the manufacturing process. - **Shrink sleeves and tamper-evident labels** leveraging BOPP’s shrinkage and high clarity. - **FMCG packaging**, or fast-moving consumer goods, where brands require high-volume, consistent label output. BOPP delivers both durability and print quality. **BOPP labels** adhere to glass, plastic, and metal containers and comply with FDA food-contact packaging requirements. This is a baseline requirement for most B2B buyers in food and pharma. ## Why BOPP Is Difficult to Print with Other Methods BOPP is highly favored in labelling and manufacturing mainly due to its moisture-resistant and tensile properties. However, if you use the wrong printing method, your labels will go to waste. Here are the reasons why BOPP cannot be used with other printing methods other than flexo printing: ### Low Surface Energy If BOPP film is untreated, it has a surface energy of approximately 30 to 36 dynes/cm. This means that ink will not adhere to it because ink requires a minimum surface energy of 38 to 42 dynes/cm. To solve this issue, BOPP film is subjected to corona or flame treatment. Most offset presses and digital inkjet systems do not integrate corona treatment in their standard equipment. ### Ink Adhesion Issues Offset UV inks and aqueous inkjet inks do not print well on BOPP, even with surface treatment. Delamination, smearing, and color shifting emerge under pressure in wet environments. Solvent-based ink systems require exhaust machinery that most offset environments do not have. ### High-Speed Production Requirements BOPP labels and packaging usually run more than 500,000 meters per run. Sheetfed presses, screen printers, and digital printers do not have high-speed roll-to-roll systems optimized for these types of products. Web tension variations cause registration problems throughout the entire run. ## Why Flexographic Printing Is the Best Solution for BOPP Flexographic printing is the industry’s proven method for BOPP substrates. Here’s why you should choose flexo printing for large-scale BOPP label production: - **High-speed printing**: Flexo presses are designed to print at 150 to 400 m/min. This speed matches the speed at which BOPP rolls are processed. It also allows factories to keep up with the huge volume of FMCG packaging requirements. - **Stable ink transfer:** The anilox roll system delivers a consistent, metered ink film. This results in uniform coverage on low-energy plastic surfaces better than any other method. - **Suitable for plastic films**: Flexo presses run standard corona treaters, anti-static bars, and nip pressure controls designed for flexible substrates like BOPP, PET, and PE. - **Cost-effective for long runs**: Flexo plate and ink costs are cost-effective in high-volume production. The per-unit costs decrease at 10,000+ meters, which is the normal range for BOPP packaging jobs. ## What Type of Flexo Printing Machine Is Used for BOPP Film? There are three flexo press configurations that are recommended for BOPP applications. Each machine is suited to a different job type and manufacturing volume. ### CI Flexo Printing Machine for High-Speed Packaging ![Large enclosed automatic film printing machine](https://www.zp-flexopress.com/wp-content/uploads/2026/05/4-3.webp) [_Full Servo Satellite Type Flexographic Printing Machine (500m/min)_](https://www.zp-flexopress.com/wp-content/uploads/wp-mfa-exports/product/full-servo-satellite-flexographic-printing-machine500m-min.md) The [Central Impression (CI) press](https://www.zp-flexopress.com/product-category/printing-machines/flexible-packaging-printing-machines/central-impression-flexo-printing-machines/) arranges all print stations around a single large drum. This design eliminates film stretch between stations and holds ±0.1mm registration accuracy across 8-color jobs. CI flexo machines handle wide-web BOPP rolls for food pouches, shrink film, and FMCG flexible packaging at speeds up to 400 m/min. ### Stack Flexo Printing Machine for Multi-Color Label Jobs ![Flexo printing press with film roll feeding](https://www.zp-flexopress.com/wp-content/uploads/2026/05/4-4.webp) [_4 Color Flexographic Printing Machine_](https://www.zp-flexopress.com/wp-content/uploads/wp-mfa-exports/product/satellite-type-4-color-flexographic-printing-machine-200m-min-water-based-ink-non-woven.md) [Stack flexo presses](https://www.zp-flexopress.com/product-category/printing-machines/flexible-packaging-printing-machines/stack-type-flexo-printing-machines/) position print decks vertically. Each deck handles one color independently. This configuration suits label converters running 4 to 8 color BOPP label designs with frequent changeovers between SKUs. Stack presses handle mid-to-high volume production efficiently without the footprint of a CI machine. ### Narrow Web Flexo Printing Machine for Label Focus ![](https://www.zp-flexopress.com/wp-content/uploads/2026/05/image-2.png) _[Satellite Type 6 Color Flexographic Printing Machine](https://www.zp-flexopress.com/wp-content/uploads/wp-mfa-exports/product/satellite-type-6-color-flexographic-printing-machine-200m-min-water-based-ink.md)_ Narrow web presses operate on web widths of 250 to 670mm. They integrate inline die-cutting, lamination, and slitting. This process turns rolls of plastic film into ready-to-use stickers. They are the ideal choice for label converters managing multiple product lines with short-to-medium run lengths. ## BOPP Film Printing Applications in the Label and Packaging Industry BOPP film is used in a wide range of commodities across different industries: - **Food packaging**: moisture- and oil-resistant labels for sauces, snacks, beverages, and dairy products. - **Shrink sleeves**: full-body label coverage on bottles and containers with high clarity and shrink conformity. - **Adhesive labels**: pressure-sensitive BOPP labels for retail shelf products across food, pharma, and household goods. - **FMCG packaging**: high-volume, continuous production for fast-moving consumer goods brands. - **Health and beauty**: waterproof labels for shampoo, lotion, and cosmetic bottles exposed to wet environments. - **Industrial and logistics**: durable identification labels for transit and warehouse environments. ## How to Choose a Flexo Label Printing Machine for BOPP Selecting the correct flexo press for BOPP production involves five technical parameters. Getting these right determines your output quality, uptime, and cost per meter. 1. Web Width Pick a machine width that fits your most common projects. For label production, a narrow web (250 to 520mm) works best. For larger packaging films, choose a wide web (800mm or more). If you plan to expand, expand the job formats to allow extra space to take on bigger jobs without having to buy a second machine. 2. Printing Speed When choosing your machine, factor in your production volume. If you mostly print labels, speeds of 150 to 200 m/min will handle the work efficiently. For high-volume packaging, choose machines that run at 300 to 400 m/min speed. Higher speed must pair with appropriate drying capacity. 3. Ink System There are three common systems for BOPP: 1. **Water-based inks** are recommended for food-contact BOPP labels. These inks require infrared or hot-air drying between stations. 2. **Solvent-based inks** have stronger adhesion on specialty BOPP grades. These inks require solvent recovery and exhaust systems 3. **UV inks** are ideal for premium finishes and fast curing. These require UV lamp or LED curing unit integration. 4. Drying System BOPP does not absorb ink. That’s why every print station needs effective between-deck drying. Otherwise, wet ink contaminates the next color. Specify hot-air dryers, IR drying banks, and a chill drum at the end of the press. UV systems simplify this with an instant cure but require compatible ink chemistry. 5. Substrate Compatibility Verify that the press handles your BOPP film thickness range. This is typically 15 to 60 microns for labels, up to 80 microns for packaging. The key press features are servo-controlled web tension, corona treater integration, anti-static bars, and adjustable nip pressure across all print stations. ## Recommended Flexo Printing Solutions for BOPP Film RAZP Flexopress offers three configured solutions for BOPP production.
