Customized Bopp laminated bags for various products

BOPP laminated bags for rice are a popular choice in the packaging industry due to their excellent properties.

Structure and Material

These bags are typically made of a laminated structure. The BOPP (Biaxially Oriented Polypropylene) layer is a key component. BOPP is a high - quality plastic film that has been stretched in two directions during the manufacturing process. This stretching gives it enhanced strength and clarity. It's often laminated with other materials such as polyethylene (PE). The PE layer usually serves as the inner layer, providing good heat - sealing properties to keep the rice well - sealed and protected from moisture.

Physical Properties

• Appearance: The BOPP laminated rice bags have a smooth and shiny exterior. The high - transparency BOPP layer allows consumers to have a clear view of the rice inside, which is an advantage for product display. They can come in different colors and designs, with vibrant printing possible on the BOPP surface to enhance the brand image and product information.

• Thickness: The thickness of the bag is designed to provide adequate strength and protection. For rice bags, the overall thickness usually ranges from 30 to 80 micrometers, depending on the weight and handling requirements of the rice package.

Mechanical Properties

• Strength: These bags have good tensile strength to bear the weight of the rice. The BOPP layer provides resistance against tearing and puncturing. When filled with rice and lifted or moved around, the bag can maintain its integrity. The strength also ensures that the bag can withstand the rigors of transportation and storage without easily breaking.

• Flexibility: Despite their strength, the bags have a certain degree of flexibility. This allows them to adapt to the shape of the rice inside and also makes them easier to handle and stack.

Barrier Properties

• Moisture Barrier: One of the most important functions of these bags is to protect the rice from moisture. The laminated structure, especially with the PE inner layer, provides an effective moisture - barrier. Rice is sensitive to humidity, and these bags can prevent the ingress of moisture, thereby keeping the rice dry and free from spoilage such as mold growth.

• Gas Barrier: The bags also offer some resistance to the exchange of gases. This helps in maintaining the freshness of the rice by reducing the access of oxygen, which can cause rancidity or other quality - degrading processes.

Printability

The smooth BOPP surface is highly suitable for printing. Brands can print detailed product descriptions, nutritional information, usage instructions, and attractive logos and graphics on the bags. The printing quality is high, with vivid colors and sharp details, which helps in product marketing and consumer recognition.

Capacity and Sizes

• Capacity: BOPP laminated rice bags come in a variety of capacities to meet different consumer and market demands. Common capacities include 1kg, 2kg, 5kg, 10kg, and 25kg.

• Sizes: The dimensions of the bags vary according to the capacity. For example, a 5kg rice bag might have dimensions of around 30cm in width, 45cm in height, and a gusset width of about 10cm. These sizes are designed to provide a convenient shape for handling, storage, and display.
