Delivery date of packaging bags

March 08, 2024

        There are two main types of packaging bags on the market today. One is a bag in stock and the other is a customized bag.

        What are the differences in the production and delivery time of these two types of bags?

Bags in stock

        General-purpose bags refer to packaging bags that are commonly used on the market. They are usually produced based on standard sizes and standard thicknesses. This type of packaging bag is often used in express delivery, supermarket shopping bags and other occasions, which can meet general packaging needs. This type of general-purpose bag is usually a transparent PE bag, a common kraft paper bag or a kraft paper composite aluminum bag, etc. However, this type of bag is not printed, and manufacturers that do not have special requirements for appearance will use this type of bag. Of course, some manufacturers pursue a minimalist style who will buy this type of bags and put company or product logos on them.

        The material structure of these bags is a common structure on the market. Generally, manufacturers have to choose appropriate bags according to the characteristics of their own products. In addition, in terms of size, universal bags are fixed. Their sizes are consistent with the existing sizes of production equipment and are also common sizes in the market. Therefore, the delivery time of general-purpose bags is generally shorter, and there are no specially customized molds, so if they are in stock, the price will be much cheaper.

Customized bags

        Compared with general-purpose bags, customized bags are much more complicated, from determining the packaging materials suitable for the customer's food, to layout design, to printing, lamination, curing, slitting, bag making, etc. The delivery time will be much longer.

        Generally speaking, it takes 7-15 days. If the order quantity is relatively large, it will take longer. Generally, installment delivery will be considered. Or if the raw materials are not in stock, the delivery time will be extended.

Material preparation - creating safe and environmentally friendly food packaging bags

        Before making food packaging bags, you first need to prepare the corresponding materials. Food packaging bags are usually made of food-grade polyethylene (PE) material because polyethylene has good chemical resistance, anti-permeability and plasticity, making it very suitable for food packaging. When selecting materials, we should pay attention to choosing materials that meet food safety standards to ensure food safety.

        In addition, in the context of pursuing environmental protection, we can also choose degradable materials to make food packaging bags. Degradable materials can decompose by themselves over a period of time, reducing environmental pollution. Choosing environmentally friendly materials not only meets the sustainable development requirements of society, but also meets consumers’ awareness and needs for product safety and environmental protection.

        The printing and design of food packaging bags is a very important part. It can not only improve the aesthetics of the packaging bags, but also enhance the brand image and recognition of the product. When printing food packaging bags, we need to choose food-grade inks and environmentally friendly printing methods.

        Commonly used food-grade inks include solvent-free ink and ink. They are characterized by fast drying, non-toxic and tasteless, do not contain heavy metals or harmful substances, and do not pollute food. Moreover, we can also use printing technology to increase the design sense of packaging bags, such as laminated printing, embossed printing, screen printing, etc., to create unique visual effects and attract consumers' attention.

Bag making processing - ensuring the quality of food packaging bags

        Bag making processing is a key link in the production process of food packaging bags. The bag making process includes steps such as die cutting, heat sealing and packaging.

        The first is die-cutting, where the pre-printed packaging film is cut into the required size and shape by a die-cutting machine. Then heat seal, and use a heat-sealing machine to heat seal the surroundings of the packaging bag to ensure the sealing and moisture-proof properties of the packaging bag. Finally, packaging is packaged, and the prepared food packaging bags are cleaned, organized and packaged for transportation and sales.

Quality inspection - ensuring food safety and quality

        After the food packaging bags are produced, quality inspection is required to ensure that they meet food safety and quality standards. Common testing items include size, sealing, tear resistance, penetration resistance, etc. After passing the quality inspection, the packaging bags can be put into use; if the quality inspection fails, the problem needs to be discovered in time and reworked or replaced.

        After the bags pass the inspection, we will send the photos and videos of the products to our customers so that they can see the effect of the produced bags at the first time.

        All in all, the production process of food packaging bags requires attention to material selection, printing and design, bag making processing and quality inspection etc.. Only through strict process and quality control can we produce safe, environmentally friendly, and attractive food packaging bags that meet consumers' requirements for food safety and appearance.
