How to calculate the thickness of PE bags suitable for your product

Polyethylene is a material accounting for more than 50% of the market share of plastic packaging industry, and low -density polyethylene (LDPE) is the source of most PE plastic bags produced. The bag is made of PE plastic, which provides large tensile strength, transparency, flexibility and impressive water prevention. It is also resistant to most alkaline compounds, acid and most importantly, the FDA approved for use as food packaging. PE bags have brought manufacturers in all industries with diverse, high quality packaging solutions with low cost, of course, with the condition that the size and thickness must be calculated correctly correctly. .

So how to calculate the appropriate thickness for PE plastic packaging?

To calculate the appropriate thickness for a PE plastic bag (polyethylene) to pack the product, you will need to consider three factors: Calculating the product to be contained inside, the ability to protect necessary for the product Your product avoids damage, and ideal durability for the packaging not to be damaged before reaching the final consumer.


• Suitable for the product: Which item you need to store inside the PE plastic bag? Consider the parameters of the product such as size, shape, and especially weight. The items are heavier and bigger than the thicker plastic bag requirements. However, the thicker the plastic membrane is reduced, so not the thicker packaging is always good.

• Protection level: Does your product need sharp or sharp edges that can tear the packaging or not, or too much of transportation and loading of goods? If one of the above factors appears, you may need a slightly thicker packaging. Delicate or more detailed items also require a slightly thicker plastic bag to prevent goods from being scratched, broken or broken.

• The use time of the packaging: Is your product consumed immediately or to save, and how long it takes to reach the user? And you or customers wishing to reuse this packaging too? A reusable bag must have at least 50 micrometers thickness, and the thicker the plastic bag, the harder it is, the harder it is to be crispy and torn when it goes through a long period of use. Some manufacturers of pillows, mattresses, suitcases ... often use thick packaging so customers can take advantage of these bags themselves in preserving, avoiding dust and product moisture when not in use. This is a particularly sophisticated thing and can create better images for the brand.

• Economic efficiency: With thinner thickness, the price of each plastic bag will be cheaper due to the use of less materials to create packaging. When the thickness increases, the cost will increase commensurate with the amount of material used. Budget factors when producing large and long -term production will need to be considered to bring economic efficiency to your business.

Understanding the size or thickness of plastic packaging will help you choose the right plan for your product. Choosing the right type of bag is very important for the success of the packaging strategy, and brings economic efficiency when saving costs. PE plastic bags that are too thin can be torn during transportation, which can cause damage to the product. On the other hand, the thickness is too large to provide a lot of protection, but brings an unnecessary yield when large -scale production


Some suggestions for choosing thickness for PE plastic bags

Plastic packaging manufacturers measure the thickness of the plastic bag with a micrometet unit (abbreviated as micron), a micrometet equal to 0.001mm and its symbol is μm.

• Ped bags from 20 to 30 microns are often used for short -term packaging types and requires low level of protection. These bags are designed to temporarily store light items such as food bags, grocery bags, sugarcane juice bags, confectionery ...

• PE bags from 40 to 50 micron are used for light or medium weight products. For example, items such as clothing, components, plastic parts, or bags used for lining in paper boxes. Plastic bags shopping in fashion shops, phones often use thickness in this range, and this is the most common thickness of plastic bags used in all industries.

• PE bags from 70 to 80 micron are suitable for average to heavy products, such as hardware components and parts, metal parts. Most plastic furniture and pillow packaging, thin mattresses are produced at this thickness. This 70 to 80 thick mic bag provides impressive anti -piercing resistance, while helping the bag can be reused many times, such as the zipper bags that we often use.

• 100 to 120 micron thick PE bags used for bulky items that packaging needs more strength to keep them in the right position. They are also used for heavy or sharp items, at risk of puncturing packaging such as bolts, screws, motorcycle parts.

• 130 to 140 micron thick PE bags for products with sharp edges or S
