We can customize roll film according to the specifications of the customer’s automatic packaging machines, including material, cycle length, width, printing, thickness, length, and orientation.
Blown film extrusion is the initial step in rollstock production. In this process, plastic resin is melted and extruded through a circular die to form a thin tube. This tube is then inflated with air to create a film bubble, which is cooled and flattened into a continuous sheet. This method ensures uniform thickness and high-quality film.
Printing is the next step, where the film is fed through a printing press to apply designs, logos, and product information. High-quality inks and advanced printing techniques ensure vibrant colors and sharp details. This step is crucial for branding and providing essential information to consumers, enhancing the product’s market appeal.
Lamination involves bonding multiple layers of film together to enhance the material’s strength, barrier properties, and durability. Adhesives or heat are used to combine the layers, creating a composite film that meets specific packaging requirements. This step is essential for products needing extra protection, such as moisture-sensitive or puncture-prone items.
After lamination, the film undergoes a drying or curing process to ensure the adhesive fully sets and the layers bond securely. This step typically involves passing the laminated film through heated chambers. Proper curing is vital for maintaining the film’s integrity and ensuring it performs well during packaging and storage.
The final step is slitting, where the large rolls of laminated film are cut into narrower rolls of the desired width. Precision slitting ensures that the rollstock fits the specifications of various packaging machines. This step is crucial for providing manufacturers with rollstock that is ready for efficient and seamless use in their packaging operations.
Choosing the appropriate material for rollstock is essential for maintaining product quality and ensuring efficient packaging. For moisture-sensitive items, high-barrier metallized films are ideal, offering excellent protection against humidity. For hard, frozen products, puncture-resistant nylon laminated films are the best choice. Each product has unique requirements, and selecting the right material ensures optimal performance, preserving product integrity and extending shelf life.
Determining the correct dimensions for rollstock is crucial for seamless packaging operations. This involves selecting the appropriate width, cycle length, and total length of the film. Tailoring these dimensions to the specific needs of the product ensures efficient use of materials and minimizes waste. Properly sized rollstock not only enhances the packaging process but also ensures that the final product is well-protected and visually appealing.
To achieve optimal performance, rollstock specifications must align with the capabilities of the automatic packaging machine. This includes considering the diameter of the paper core, the weight of each roll, and the film unwinding direction. Ensuring compatibility between the rollstock and the machine prevents operational issues and maximizes efficiency. By carefully selecting rollstock specifications, manufacturers can streamline their packaging processes and maintain high production standards.
Rollstock is a versatile packaging solution widely used in the food industry, offering efficiency and reliability for a variety of products. One of the most common applications is in the automatic packaging of snacks like potato chips. The high-speed packaging machines utilize rollstock to form, fill, and seal the bags, ensuring that the chips remain fresh and crispy. The material’s excellent barrier properties protect against moisture and oxygen, preserving the product’s quality and extending its shelf life.
In addition to snacks, rollstock is also ideal for packaging beverage powders. These products require a high level of protection to maintain their flavor and nutritional value. Rollstock materials, such as metallized films, provide the necessary barrier against moisture and light, ensuring that the powders stay dry and potent. The flexibility of rollstock allows for various packaging formats, from single-serve sachets to larger, resealable pouches, catering to different consumer needs.
Rollstock is also used as lidding film for plastic food containers. This application is particularly important for ready-to-eat meals, dairy products, and other perishable items. The lidding film must provide a secure seal to prevent contamination and leakage while being easy to peel off for consumer convenience. High-quality rollstock materials ensure that the lidding film adheres well to the container, maintaining the product’s freshness and safety.
