The roll of plastic bags is made from materials such as nylon (plastic) that are produced in a roll form through the plastic manufacturing process. These bags have perforations or small slits throughout their length that allow for easy separation. This feature of the roll of plastic bags enables the user to easily detach the bag from the roll and use it when needed.

The use of roll plastic bags is common in the retail and shopping industry, the food and beverage industry, the medical and pharmaceutical industry, the electronics industry, and many other industries. These bags are recognized as a suitable alternative to traditional and disposable bags due to their lightweight, high strength for transportation, resistance to moisture and water, recyclability, and reduction of environmental pollution.

What is a perforated roll plastic bag?

A perforated roll plastic bag is a type of plastic bag that is produced in a roll form and has perforations (punch holes) on its surface. These perforations are arranged in various and regular patterns on the surface of the bag. They are primarily used for convenience and ease of use.

These bags are usually made from materials such as lightweight polyethylene (LDPE) or heavy-duty polyethylene (HDPE) that are suitable for resistance to breaking and tearing. The perforated roll plastic bag is used in many industries, including food, agriculture, industrial, and service sectors.

Dimensions and thickness of roll plastic bags

The dimensions and thickness of roll plastic bags may vary and depend on customer needs. Dimensions usually refer to the width and length of the bag, while thickness refers to the weight and base thickness of the bag. The dimensions of roll plastic bags can range from small and miniature sizes to large and industrial sizes, depending on customer requirements. Additionally, the thickness of roll plastic bags is usually measured in micrometers (microns) and may vary in ranges such as 20 microns, 30 microns, 50 microns, etc. However, please note that the exact dimensions and thickness may vary based on the order and manufacturer.

What is the difference between a handle plastic bag and a perforated roll plastic bag with handles?

Handle plastic bags and perforated roll plastic bags with handles are two different types of plastic bags. Below, I will explain the differences between the two:

1. Handle plastic bag: This type of bag has a fixed shape and design and is made in the form of a box or handle (with a base and two sides). Handle plastic bags are generally made from lightweight plastic such as lightweight polyethylene (LDPE). The handle design of this bag allows it to stand vertically and hold its internal contents. Since handle plastic bags have a fixed shape and base, they are commonly used in the retail industry, kitchens, food industry, and service sectors.

2. Perforated roll plastic bag with handles: This type of bag also has a handle shape but has perforations (punch holes) on its surface. The perforations are arranged in various and regular patterns on the surface of the bag. Perforated roll plastic bags with handles are also generally made from lightweight plastic such as lightweight polyethylene (LDPE). These bags may be used for purposes such as ventilation, water drainage, and in industries that require airflow and changes in air. The perforations allow the bag to transfer air and materials and are suitable for various purposes such as food, agriculture, and service industries.

In summary, the main difference between handle plastic bags and perforated roll plastic bags with handles is the presence of perforations on the surface of the bag. Both types of bags are used in various industries depending on customer needs.

What is the difference between nylon and plastic?

The main difference between nylon and plastic lies in the raw materials used for their production and their physical and chemical properties. Below, I will explain the key differences between nylon and plastic:

1. Raw material: Nylon is usually made from polyamide, while plastic is made from polyethylene. Polyamides and polyethylenes have different properties, and consequently, nylon and plastic differ in their physical and chemical characteristics.

2. Strength and durability: Nylon generally has higher strength and durability compared to plastic. Nylon has good resistance to tension, impact, and abrasion and is required for certain applications that need high strength. In contrast, plastic has lower tensile strength and durability and is mainly used for light and medium applications.

3. Flexibility and transparency: Nylon is more flexible than plastic and can be used in various forms and structures. Additionally, nylon naturally has high transparency and impermeability. In contrast, plastic generally has lower transparency and can be produced in various shapes and colors.

4. Chemical resistance: Nylon generally has higher chemical resistance compared to plastic. Nylon has better resistance to solvents, oils, chemicals, and heat. In contrast, plastic is more sensitive to certain chemicals such as acids and bases and may deform or be damaged under their influence.

Production of roll plastic bags with granule and carbon raw materials (grade 2 and 3 materials)

The production of roll plastic bags using granule and carbon raw materials (grade 2 and 3 materials) is related to the plastic manufacturing process. In this process, granule and carbon materials (LDPE) can be used as raw materials.

The stages of producing roll plastic bags generally include the following:

1. Processing raw materials: In this stage, granule and carbon materials (grade 2 and 3 materials) undergo various plasticizing processes such as injection, kneading, or continuous pressure. These processes prepare the materials for the subsequent stages of production.

2. Extrusion: In this stage, the heated and prepared plastic materials are transferred from a reservoir to an extrusion machine. In extrusion, materials pass through a mold via a piston or rod and emerge in the form of a plastic tube.

3. Shaping and cutting: The cooled plastic tube is shaped into rolls on special machines. In this stage, using appropriate materials and equipment, the plastic tube is transformed into roll bags. Then, using a cutting machine, the roll bags are cut to the required length and prepared for packaging.

4. Packaging: The roll plastic bags that have been cut to the required length are packaged in rolls. These rolls are placed in suitable packaging depending on the needs and destination.

Grade 2 and 3 materials are also used as raw materials in this process. These grades are usually selected according to the various uses for which roll plastic bags are employed. Each grade has specific properties and characteristics that are utilized based on customer needs and various applications.

Colored roll plastic bags

Colored roll plastic bags are a type of plastic bag produced using LDPE materials and adding color to the raw material. These bags are usually available in various types and sizes and are used for diverse purposes.

Diverse colors can be added to the LDPE material to make the bags colored. These colors can be uniform across the bag's surface or include various patterns and designs. Common colors for roll plastic bags include white, black, red, blue, green, yellow, etc. Additionally, mixed colors can be used to produce multicolored bags.

Colored roll plastic bags may be used for various purposes, including packaging products, household uses, advertising and promoting brands, service and industrial businesses, etc.

Design and printing of roll plastic bags

The design and printing of roll plastic bags is one of the important factors in the packaging industry that helps companies present their products attractively and professionally to customers. In the design of roll plastic bags, the most important element is the packaging design, which includes patterns, shapes, colors, and decorative items. Proper design meets customer needs and effectively showcases the brand and product.

Printing on roll plastic bags can be done on the outer surface of the bag, allowing companies to print logos, brand names, product images, contact information, and other necessary information on the bag. Various techniques are used for printing roll plastic bags, including flexographic printing, rotogravure, offset, and screen printing.

To achieve high-quality and attractive printing on roll plastic bags, it is essential to consider factors such as choosing appropriate colors, using precise images and patterns, utilizing suitable fonts and writing styles, and employing advanced technologies in printing. Additionally, adhering to international standards such as using durable and environmentally friendly printing materials is also important.
