Diversified Classification of Bags

Table of Contents

Bags play an indispensable role in our daily lives and are meticulously classified according to different purposes and characteristics. Firstly, from the perspective of style, bags can be divided into women’s bags, men’s bags, travel bags, student bags, and hiking bags designed specifically for outdoor enthusiasts. These styles not only meet the needs of different groups of people but also showcase their respective fashion and practicality.

In terms of materials, bags also offer a rich selection. From traditional leather bags and fabric bags to modern popular PU bags, PVC bags, and canvas bags, each material has its unique advantages and suitable scenarios. Leather bags are favored for their noble elegance, while canvas bags are loved by young people for their lightweight and durability.

In addition to style and material, the functionality of bags is also an important criterion for classification. For example, laptop bags, briefcases, digital bags, etc., are designed to provide secure protection and convenient carrying for specific items. Moreover, makeup bags, camera bags, instrument bags, fishing bags, etc., also reflect the professionalism and practicality of bags in specialized fields.

Furthermore, we need to specifically mention trunk-style bags. These types of bags are usually large in volume, sturdy in structure, and suitable for storing more items. Representative examples of trunk-style bags include wheeled luggage, suitcases, hand luggage, and toolboxes. They not only provide convenience for travel and business trips but also serve as a medium for people to showcase their personalities and tastes.

Detailed Explanation of Bag Materials

The selection of materials is crucial in bag production. Firstly, genuine leather stands out as a top choice among bag materials. It comes from various animal hides such as cowhide, sheepskin, and pigskin. Genuine leather is porous with good breathability but prone to moisture absorption. It has a soft and smooth texture, irregular grain patterns, making it the preferred material for crafting high-end bags.

However, there are also synthetic leather materials in the market, such as PU and PVC. While these materials resemble genuine leather in appearance, they differ in performance. The difference between PU and PVC lies in the thickness of their base fabric and softness. Additionally, these two materials can be distinguished through a burning test. PU leather exhibits better physical properties, such as flexibility, tensile strength, and some breathability.

Apart from genuine leather and synthetic leather, canvas and Oxford cloth are also commonly used materials in bag production. Canvas is known for its thick and durable characteristics, making it suitable for crafting waterproof bags. On the other hand, Oxford cloth boasts features like easy cleaning, quick drying, soft texture, and good moisture absorption, making it an ideal material for casual bags.

Lastly, we need to mention a special type of leather – patent leather. Patent leather is actually a manufacturing process that involves grinding scraps of genuine leather into a pulp. It has a strong plastic feel and a shiny appearance. Wrinkled patent leather is one of the widely used materials, offering good texture, softness, while retaining some characteristics of cowhide. Bags made from it are very comfortable. However, it’s important to note that patent leather is a concept rather than a material itself.

Classification of Bag Hardware and Structural Terminology of Important Parts

Classification of Bag Hardware

The hardware fittings installed on bags not only enhance their aesthetics but also are crucial for their durability. These hardware fittings include zippers, metal rings, metal buckles, rivets, and metal logos, among others. The quality of hardware fittings is an important aspect in assessing the grade of bags; high-quality hardware not only looks exquisite but also has strong durability.

Structural Terminology and Characteristics of Important Parts of Bags

Shoulder Strap (Handle):

Structure: Consists of two layers, with PVC or leather pulp sandwiched in between.

Connection: Typically utilizes hooks or circular metal rings, with alloy die-cast circular rings offering better quality.


Components: Comprises zipper, slider, and puller.

Identification methods:

Check whether the zipper teeth are falling off.

Pull the slider to check if the connection is smooth.

Bend the zipper to check for cracks.

Observe the gap between the puller and the slider.

Characteristics of metal zippers: Smooth sliding, quiet sound, firm and not easily deformed.

Bag Body:

Structure: Comprises three layers, with the outer layer being the fabric, the middle layer being a backing material like PVC or other materials, and the inner layer being the lining.

Identification methods: The material of the middle layer can be judged by touch.


Classification: Natural leather, PU leather, PVC material, nylon material, canvas, plush fabric, etc.


The top layer leather has high quality and is used for mid-to-high-end bags.

Split leather is used for mid-to-low-end bags.

PU leather and PVC material are synthetic leather, with PU leather usually of better quality.

Identification of Metal Materials:

Differentiate between “iron wire” and “alloy”: Use a magnet test, iron wire can be attracted tightly, while alloy cannot.

Alloy hardware is usually more exquisite and expensive.

Oil-sealed metal hardware is not easy to oxidize and rust, which can be judged by smell and touch.

Bronze-plated hardware is prone to rusting, so it should avoid rainwater and be promptly dried.

Thread (Stitching):

Outer stitching commonly uses thicker nylon thread, inner stitching uses finer nylon thread, and lining uses cotton thread.

Color should match the fabric for visual coordination.


Understanding the classification of bag hardware and the structural terminology and characteristics of important parts helps us make wiser choices when purchasing bags. High-quality hardware and reasonable structural design not only enhance the durability of bags but also increase their aesthetics and practicality. Meanwhile, paying attention to the material and craftsmanship of hardware, as well as the selection of fabrics, is crucial to ensuring the quality of bags.

Care, Maintenance, and Cleaning Tips for Leather Bags


Daily Use:

Avoid contact with sharp objects to prevent scratches.

Regularly use specialized leather care oil to maintain the softness and luster of the leather.

Rotate the use of different leather bags to give each bag some rest time.

Maintenance for Different Leather Types:

Common Leather: After removing dust, use specialized cleaning oil and care oil for maintenance.

Suede Leather: Use a soft animal hair brush to remove dust, and avoid contact with oil stains and adhesive substances.

Patent Leather: Handle with extreme care to prevent cracks. If there are cracks, gently wipe with specialized grease.


Cleaning and Drying: Ensure the bag is completely clean and dry before storage.

Padding and Protection: Fill the bag with old newspapers or specialized fillers to prevent deformation.

Moisture and Dust Prevention: Place the bag in a specialized moisture-proof or dust-proof bag and store it in a dry and ventilated place.

Avoid Pressure and Stacking: Avoid placing heavy pressure on or stacking bags to prevent damage or deformation.


Common Dirt: Use an eraser to gently remove, or clean with dishwashing detergent and warm water.

Ballpoint Pen Marks: Blot out excess ink with a tissue, then clean with gasoline, white wine, or methylated spirit, followed by professional leather stain remover.

Severe Stains: Deep clean with dishwashing detergent and warm water, then air dry and apply care oil.

Scratch Treatment: Use a colored crayon of the same color as the bag to repair scratches, gently wipe to let the crayon penetrate the leather.
