What is Printed Film

Film food packaging involves an oriented polyester film with a heat-sealed surface that is externally exposed to very high temperatures. The heat energy is then transferred, creating a secure and airtight seal for the food. Roll film is a packaging film with many advantages in the food packaging industry. The main advantage is cost savings in the entire packaging process. The application of roll film in automatic packaging machinery does not require the packaging production company to perform any edge sealing work, and only requires the production company to perform a one-time edge sealing operation. This not only saves time but also reduces labor costs, making it an efficient choice for food packaging companies.

Benefits of Printed Film

Cost-effective

The production of rollstock film is extremely efficient in its usage of materials. The process uses continuous rolls of flexible material, allowing for the high-volume production of rollstock packaging. This reduces the amount of waste produced and the cost of production. You can also save on your shipping and storage costs with rollstock film. Since this product is so lightweight, it costs less to ship and store.

Better product protection

Rollstock packaging provides great protection to products. This film includes advanced sealing technologies that ensure the freshness and integrity of the packaged products. There are rollstock films that protect against oxygen, moisture, and light, all of which are crucial to protecting the quality of food, beverages, and various other products.

Produces packaging at a higher speed and efficiency

Rollstock can be used in automated packaging processes which results in higher production. These automated processes are faster and more accurate than manual or semi-automated methods and automated machines can run around the clock if desired, leading to even more production.

Storage space savings

Since rollstock packaging is created from flexible materials, it can easily be compacted to fit into storage spaces. This allows for more products to be stored in the same place because it is so flexible it can conform to its surroundings. Since more products can be stored in the same space, this results in lower storage costs.

Suitable for sterilization

Rollstock films are often preferred because of their compatibility with many different sterilization methods. This packaging material is compatible with heat sterilization, gamma radiation, ethylene oxide (ETO) sterilization, and electron beam sterilization.

Usage of Printed Film

Food packaging field

In the field of food packaging, packaging roll film is undoubtedly a strong defense line for food safety. Imagine that from the farm to the table, freshly picked fruits and vegetables are carefully processed and wrapped in a thin yet tough packaging roll film, effectively blocking the invasion of moisture, oxygen, and microorganisms from the outside world, maintaining the color, taste and nutritional components of the fruits and vegetables. Not only that, for processed foods, such as pastries, meat products, etc., packaging roll film can provide good air tightness, prevent the loss of fragrance and oxidation of grease, and extend the shelf life of the food. For example, the packaging of frozen food we often see, packaging roll film can not only resist low temperatures but also prevent frosting and moisture penetration, ensuring that the food remains of high quality in the frozen state.

Pharmaceutical industry

In the pharmaceutical industry, the importance of packaging roll film is self-evident. The stability and effectiveness of drugs are directly related to the health of patients, and packaging roll film plays a key role in it. It can strictly control the interaction of drugs with the external environment and avoid the influence of light, humidity, and temperature on drugs. Some special packaging roll films also have the functions of moisture-proof, oxygen-proof, and volatile-proof to ensure that the active ingredients of drugs remain stable during the validity period. For example, some highly sensitive biological preparations and vaccines require the use of packaging roll films with extremely high barrier properties to ensure their efficacy and safety.

E-commerce field

When we turn our attention to the rapidly developing e-commerce field, packaging roll film also shows strong adaptability and practicality. In the busy logistics and distribution, countless goods experience bumps and collisions during transportation. At this time, packaging roll film can be used as a buffer material to provide additional protection for fragile items. At the same time, it can also be used to wrap the entire batch of goods to prevent the goods from spreading or being damaged during transportation. Moreover, with the continuous growth of personalized packaging needs, e-commerce enterprises can use finely printed packaging roll film to create a unique unboxing experience for consumers and enhance the interaction and emotional connection between the brand and consumers.

In industrial production

In industrial production, packaging roll film also plays an indispensable role. All kinds of parts, raw materials, and finished products need appropriate packaging to ensure their quality during storage and transportation. Packaging roll film can be customized according to the needs of different industrial products, providing various protection functions such as rust-proof, dust-proof, and anti-static. For example, in the automotive manufacturing industry, engine parts, electronic components, etc. all need to use specific packaging roll films to ensure they are not damaged in the complex production and logistics links.

How to Choose the Right Printed Film

Determine the type of packaging material needed

The first step is to determine what type of material is needed for the product being packaged. Roll stock can come in a variety of materials, such as plastic films, paper, foil, and laminates. Consider factors such as the product's shelf life, moisture resistance, and barrier properties when selecting a material.

Normally for the snack packaging roll stock ,such as chips packaging,candy packaging,chocolate bar packaging,popcorn packaging ,the material is made by couple layers of plastic film or paper film,and are often used to provide a combination of barrier properties and aesthetic appeal. For example, a laminate may consist of a layer of foil to provide barrier protection and a layer of PET for clarity and printability.

Calculate the required thickness

The thickness of the roll stock should be calculated based on the product's weight, size, and shape. Thicker materials can provide better protection, but they can also increase costs and affect the machine's performance.

Each packing machine has a maximum thickness limit for the roll stock that can be used with it, which is typically determined by the design of the sealing and cutting mechanisms.

To determine the maximum thickness of roll stock that can be used with a specific packing machine, you should consult the machine's manual or contact the manufacturer. In general, most packing machines can handle roll stock with a thickness ranging from 0.0005 inches (0.0127 mm) to 0.025 inches (0.635 mm), but this can vary depending on the machine's design.

It is important to note that using roll stock that is too thick for the machine can cause problems such as uneven sealing or cutting, increased wear on the machine's parts, and decreased efficiency. Similarly, using roll stock that is too thin can result in poor quality seals and packaging failure. Therefore, it is essential to select the appropriate roll stock thickness that is compatible with the packing machine to ensure optimal performance and quality of the final product.

Determine the roll width and length

The width and length of the roll stock will depend on the dimensions of the packaging machine and the product being packaged. It's important to choose a roll width that fits the machine and a roll length that minimizes waste and downtime.

Measure the size and shape of the product: The first step is to measure the size and shape of the product being packaged, including its length, width, and height. This will help determine the minimum dimensions required for the roll stock.

Determine the packaging machine's specifications: The packaging machine's specifications, such as its maximum sealing and cutting width, will also determine the width and length of the roll stock that can be used. Consult the machine's manual or contact the manufacturer to determine its specifications.

Calculate the roll width: Once the minimum width required for the product and the maximum sealing and cutting width of the machine have been determined, calculate the roll width by adding a margin for sealing and cutting. For example, if the product requires a minimum width of 3 inches and the machine has a maximum sealing and cutting width of 6 inches, add a margin of 1 inch on each side for sealing and cutting, resulting in a roll width of 8 inches.

Calculate the roll length: The roll length should be calculated to minimize waste and downtime while ensuring that enough roll stock is available for packaging. This can be calculated by dividing the product's total length by the number of products that can be packaged per roll. For example, if the product's length is 2 inches and 100 products can be packaged per roll, the roll length should be at least 200 inches.

By following these steps, the appropriate width and length of the roll stock can be determined for efficient and cost-effective packaging. It is important to work with a reputable supplier who can provide roll stock in the required dimensions and ensure compatibility with the packaging machine.

Consider the sealing method

The type of sealing method used by the packaging machine can affect the type of roll stock needed. For example, some machines use heat sealing, while others use ultrasonic sealing. Make sure the roll stock is compatible with the machine's sealing method.

Evaluate the supplier's quality and reliability

Finally, it's important to choose a reliable supplier that offers high-quality roll stock. Look for a supplier with a good reputation, experience in the industry, and a track record of delivering on time and on budget.
