Description

What is OPP tape?

OPP tape (oriented polypropylene tape) uses biaxially oriented polypropylene film as its base material. The adhesive surface is mostly transparent, with good tensile strength and cost-effectiveness, making it one of the most widely used types of packaging tape on the market.

Key features of OPP tape:

High transparency, clearly displaying the contents of the packaging or labels.
Good adhesion, suitable for sealing cartons and common packaging materials.
Noticeable noise during use; a “hissing” sound is produced during application.
Affordable, suitable for bulk purchases and high-volume applications.

Applications of OPP carton sealing tape

Shipping and express delivery packaging: Sealing and securing cartons to prevent goods from being opened or damaged during transportation.
E-commerce and online shopping products: Improving packaging efficiency, maintaining brand image, and ensuring a stable shipping process.
Electronic product packaging: Sealing and protecting product or electrical equipment boxes.
Stationery and household applications: Daily labeling, packaging, or storage.

OPP adhesive tape production process

The OPP adhesive tape (BOPP tape) production process mainly includes high-voltage corona discharge treatment (to increase surface tension), pressure-sensitive adhesive coating (water-based adhesive or hot-melt adhesive), drying/curing, slitting, and packaging. The core material is biaxially oriented polypropylene (BOPP) film, which is coated with an adhesive layer to produce tape with extremely high adhesion and tensile strength.

Detailed production process for raw material preparation and treatment (Corona discharge treatment)

Base material: Use raw BOPP film. This film is biaxially oriented and has excellent toughness.
Corona discharge treatment: Since the surface of BOPP film is relatively smooth, high-voltage corona discharge treatment is required before adhesive coating. This step increases the surface tension of the film, ensuring that the adhesive bonds firmly to the film.
Adhesive coating: A pressure-sensitive adhesive emulsion is evenly coated onto the surface of the corona-treated BOPP film.
Adhesive type: Water-based acrylic adhesive or hot-melt synthetic rubber is commonly used.
Drying and curing: The coated film is fed into a drying oven and heated to dry it, causing moisture or solvent in the adhesive to evaporate, thereby allowing the adhesive to bond firmly to the substrate.
Slitting and rewinding: The wide-width adhesive-coated film roll is slit into smaller rolls according to different specifications (such as common widths) using a fully automatic slitting machine. This step also performs rewinding, namely winding the tape into the required length.
Packaging: The slit tape is printed, peeled or packaged in cartons, and then used for sealing during transportation.

Key features of the process:

High adhesion: Through high-quality corona treatment and a special pressure-sensitive adhesive formulation, the tape ensures good weather resistance, tensile strength, and pressure resistance for various types of packaging seals.
Environmentally friendly: Modern OPP tape mainly uses water-based acrylic pressure-sensitive adhesive, which is more environmentally friendly.
Application areas: Mainly used for daily packaging, heavy-duty sealing, industrial packaging, etc.

How to choose high-quality OPP tape?

When buying OPP tape, the main factors to consider when evaluating quality are:

1. Thickness and adhesive layer

The total thickness of the tape includes both the film and adhesive layers. A thicker film and more evenly distributed adhesive layer provide better adhesion and higher tear resistance.

2. Type of adhesive

The most common type is acrylic adhesive. For cold resistance, choose cold-resistant/freezer-grade adhesive. Stable adhesion and no residue are preferred.

3. Brand and origin

You should choose a reputable tape supplier with stable operations and good after-sales service. This ensures consistent quality, high durability, and quick problem resolution.

Storage of OPP Tape

OPP tape should be stored in a dry, cool, well-ventilated place, away from direct sunlight and high freezing temperatures. The optimal storage temperature is the missing temperature value, with humidity below 65%. It should be stored vertically, avoiding strong pressure and kept away from organic solvents and sharp objects. The typical shelf life is 3 years.

Here are the specific storage recommendations:

Environmental requirements: Store in a dry, clean warehouse, avoiding storage together with organic solvents, metals, and sharp objects.
Temperature control: The recommended temperature range is between 15°C and 25°C. Excessively high temperatures will soften the tape and cause air bubbles, while excessively low temperatures will reduce adhesion.
Avoid light: Sunlight will accelerate the aging of the tape, causing the backing material to become brittle and the adhesive to deteriorate. Store in a dark place.
Proper storage: The tape should be packaged in rolls. Do not break the seal if not in use. It is best to store the tape rolls vertically to avoid stacking them, as stacking may cause the tape to become crushed and deformed in the middle.
Shelf life management: Use according to the “first in, first out” principle. Although OPP tape generally has a shelf life of 3 years, using it beyond this period may affect its adhesion.

If the tape becomes damp before use, its adhesion will decrease; it should be placed in a well-ventilated area to dry.

How to choose OPP tape

OPP tape can be purchased on e-commerce platforms such as Shopee and Lazada, Tiki, Sendo or at hardware and stationery stores. When choosing, pay attention to the brand (for example: Hadupack, 3m, Nitto, Tesa), adhesion, thickness and width. This type of tape is commonly used for sealing boxes (a box sealing machine should be used), gift packaging, etc., and usually has a width of 48mm. The material includes OPP/BOPP; choose the appropriate tensile strength based on the load-bearing requirements.

Points to note when choosing:

Thickness and adhesion: Higher-adhesion and thicker tape is needed for sealing heavy items; tape with standard thickness is sufficient for quickly shipping ordinary lightweight items.
Brand: Popular brands on the market include Hadupack tape, 3M tape, Tesa adhesive tape, Nitto tape, etc.
Size: The common width for sealing boxes is or the length depending on requirements (for example: 50 meters, 100 meters).
Accessories: It is recommended to use it with a box sealing machine (cutter) to improve efficiency.

Note: High-quality OPP tape has high transparency, strong adhesion, is non-toxic and odorless.

Frequently Asked Questions About OPP Tape

Q1: Does noise-free tape always use water-based adhesive?

A1: No. Both water-based and solvent-based tapes can achieve noise-free performance through process optimization. Therefore, the type of adhesive and the noise-free characteristics of the tape are not directly related to each other.

Q2: Which type of tape should I choose if I mainly ship goods in large quantities?

A2: If cost is a concern and noise is not a major issue, we recommend regular transparent OPP tape, which offers good value and is suitable for large-volume shipments. If the packaging environment prioritizes ease of handling and quiet operation, noise-free tape is recommended.
