Tote bag product parameters and manufacturing process

1、 Product parameters

（1） Material

The material selection of tote bags is rich and diverse, and different materials endow tote bags with different characteristics and styles, meeting the needs of different scenarios.

Canvas: Made of high-quality cotton canvas, typically weighing between 240g and 400g. 240g canvas material is relatively lightweight, suitable for making simple and lightweight tote bags, easy to carry; 400g canvas is thicker, firmer, more durable, and can withstand heavier objects, making it suitable for daily commuting or shopping. All cotton material has good breathability and moisture absorption, soft and comfortable hand feel, and is environmentally friendly and healthy.

Oxford cloth: available in various specifications such as 600D, 800D, 1680D, etc. The higher the D number, the higher the density of the fabric, and the stronger the wear resistance and tensile strength. 600D Oxford cloth has a lightweight texture and good waterproof performance, suitable for making outdoor leisure style tote bags; 1680D Oxford cloth is very sturdy and durable, commonly used for tote bags that require carrying a large number of items, such as travel tote bags. Oxford cloth also has good wrinkle resistance and is relatively easy to maintain.

Leather: including genuine leather and synthetic leather. The genuine leather is made of high-quality top layer cowhide, sheepskin, etc., which have natural texture and luster, delicate touch, and will present a unique patina with increasing use time. The texture is excellent, but the price is relatively high. Artificial leather imitates genuine leather in appearance, is more affordable, and has good wear resistance and waterproofness. It is easy to clean and maintain, suitable for consumers who pursue fashion and cost-effectiveness.

（2） Specifications

The specification design of tote bags should balance practicality and aesthetics. Common specifications are as follows:

• Length: 30cm -50cm. A length of around 30cm is suitable as a compact handbag, making it easy to carry a small amount of items; A length of around 50cm can accommodate more items such as laptops, books, clothing, etc., meeting the needs of daily work, study, and travel.

Width: 10cm-20cm. Narrow width tote bags appear more delicate and suitable for pairing with casual clothing; A wider tote bag has stronger storage capacity and can better accommodate items of various shapes.

• Height: 25cm -40cm. A tote bag with a moderate height is more convenient to use, as it can accommodate a large number of items without appearing too bulky.

（3） Performance

• Load bearing capacity: Depending on the material and manufacturing process, the load-bearing capacity of tote bags also varies. Generally speaking, the load-bearing capacity of canvas and Oxford tote bags ranges from 5kg to 15kg, while the load-bearing capacity of leather tote bags can reach 10kg to 20kg, which can meet the weight requirements of daily carrying items.

Waterproof performance: Oxford tote bags are usually treated with waterproofing and have good waterproof performance, which can effectively resist the invasion of rainwater and stains; Canvas tote bags can also have certain waterproof properties after special treatment; Leather tote bags have relatively poor water resistance and need to avoid prolonged exposure to water.

Durable performance: High quality tote bags are made of high-strength fabrics and exquisite manufacturing techniques, with excellent durability. Canvas and Oxford tote bags have strong durability and are not prone to pilling or cracking; Leather tote bags can have a lifespan of several years or even longer under normal use and maintenance.

2、 Production process

（1） Fabric processing

• Pre treatment: The fabric needs to be pre treated before use, including steps such as cleaning, desizing, bleaching, etc. Cleaning can remove impurities and dust from the surface of the fabric; Resizing is to remove the slurry on the fabric, making it softer and more breathable; Bleach can make the color of the fabric whiter and more uniform, preparing for subsequent printing and dyeing.

• Shaping: Pre treated fabrics need to undergo shaping treatment, such as high-temperature ironing, to stabilize the size of the fabric and avoid shrinkage or deformation during production and use.

（2） Printing process

There are various printing techniques for tote bags, and suitable printing methods can be selected according to customer needs and design patterns.

Screen printing: This is a commonly used printing process that transfers ink onto the fabric through a screen. Screen printing has the advantages of bright colors, strong adhesion, and good washability, making it suitable for printing simple patterns and text, and relatively low cost, making it suitable for large-scale production.

Digital printing: Using digital technology to directly print patterns on fabrics, it has the characteristics of clear patterns, rich colors, and strong layering, which can meet the printing needs of complex patterns. Digital printing does not require plate making, has a short production cycle, and is suitable for small batch, personalized orders, but the cost is relatively high.

Heat transfer printing: First, print the pattern on transfer paper, and then transfer the pattern to the fabric through high temperature. The pattern of heat transfer printing is bright and realistic in color, with strong adhesion and good washing resistance, suitable for printing various complex patterns and photos, and widely used in the production of personalized tote bags.

（3） Cutting process

Cut the processed fabric according to the design drawings and specifications. Accurate cutting tools such as scissors and cutting machines are required during cutting to ensure accurate fabric size and neat edges. For fabrics with patterns, it is also important to pay attention to the alignment and integrity of the patterns to ensure the aesthetic appeal of the tote bag.

（4） Sewing process

Sewing is a crucial step in the production of tote bags, directly affecting their quality and durability.

• Needle and thread selection: Choose the appropriate needle and thread based on the material and thickness of the fabric. For thicker fabrics such as canvas and Oxford cloth, thicker needle and thread should be selected to ensure the firmness of sewing; For leather fabrics, specialized leather needle and thread are required to avoid damaging the fabric.

Sewing method: Double line or multi line sewing is used to enhance the strength of the seams. At the edges, handles, and other stressed areas of the tote bag, reinforcement stitching such as jujubes and edge wrapping is also required to improve the durability of the tote bag. During the sewing process, it is necessary to ensure that the stitches are uniform and flat, without any jumping or missing threads.

（5） Accessory installation

The accessories of a tote bag include handles, zippers, buckles, etc. The installation of the accessories needs to be firm and aesthetically pleasing. The handle is usually made of the same or similar material as the fabric, and is fixed to the bag body by sewing or rivets; Zippers and buckles require the selection of reliable products, ensuring smooth and secure installation, and easy use.

（6） Post processing

• Ironing: The finished tote bag needs to be ironed at high temperatures to make the shape of the bag more firm and flat, removing wrinkles generated during the sewing process.

• Inspection: Conduct a comprehensive inspection of the tote bag, checking the quality of the fabric, printing effect, sewing quality, and installation of accessories to ensure that they meet the requirements and that the product quality is qualified.

• Packaging: Packaging qualified tote bags, usually using plastic bags, paper boxes, and other packaging materials, to protect the product from damage during transportation and storage, while also facilitating sales and carrying.
