If you&#;re selling products, chances are you&#;ve had to decide which type of packaging to use. With so many options on the market, it can be difficult to know which one is right for your product. Do you need one that&#;s easy to open? Or maybe you&#;re looking for something that&#;s both durable and cost-effective. In this article, we will help you understand how to differentiate paper poly bags.

The three most common types of packaging are BOPP, OPP, and PP bags. But what&#;s the difference between them? Keep reading to find out.

BOPP Bags

BOPP bags contain biaxially-oriented polypropylene. They&#;re strong and resistant to tearing, making them a good option for products that are likely to get handled roughly. BOPP bags also have a high resistance to moisture and heat, so they&#;re a good choice for food products that need to stay fresh.

One downside of BOPP bags is that they&#;re not biodegradable. So, if you&#;re looking for an eco-friendly option, this isn&#;t it. BOPP bags are also not transparent, so if you need your product to be visible, you&#;ll need to choose a different type of packaging.

OPP Bags

OPP is short for oriented polypropylene. They&#;re like BOPP bags in that they&#;re strong and resistant to tearing and moisture. They also have a high resistance to heat, making them a good option for food products. However, OPP bags are more flexible than BOPP bags, making them easier to open. They&#;re also transparent, so your product will be visible inside the bag.

Their high tensile strength makes them ideal for products that are likely to get handled roughly. Like BOPP bags, OPP bags are not biodegradable. And because they&#;re more flexible than BOPP bags, they offer less protection against crushing and impact damage.

PP Bags

PP bags contain polypropylene. They offer similar benefits to BOPP and OPP bags in terms of strength and resistance to moisture and heat. However, PP bags are more rigid than BOPP and OPP bags, offering more protection against crushing and impact damage. They&#;re also transparent, like OPP bags, so your product will be visible inside the bag.

One downside of PP bags is that they&#;re not as easy to open as OPP bags. And like both BOPP and OPP bags, they&#;re not biodegradable.

How Are BOPP, OPP, and PP Bags Similar?

All three types of bags contain polypropylene. This material makes them strong and resistant to tearing. They also all have a high resistance to moisture and heat. The tear resistance makes them a good choice for products that are likely to get handled roughly. And the moisture- and heat-resistance makes them a good choice for food products.

With S&K packaging, our paper poly bags can also feature anti-skid, EasyOpen, and Micro Perforations for extra functionality.

When Should You Use BOPP, OPP, or PP Bags?

Now that you know the difference between BOPP, OPP, and PP bags, you can decide which is suitable for your product. If you need a strong, durable option that protects against crushing and impact damage, go with a PP bag. If you need an option that&#;s easy to open and offers good visibility for your product, use an OPP bag. And if you need a strong and durable option resistant to moisture and heat, opt for a BOPP bag.

Remember, there&#;s no one-size-fits-all answer when it comes to packaging. The type of bag you choose will depend on the needs of your product. So, take some time to consider what&#;s important to you and make a decision that&#;s best for your business.

Packaging is a necessary part of any product-based business. The proper packaging can make your product more attractive to customers and help it stand out from the competition. But with so many options on the market, it can be difficult to know which type of packaging is right for your product.

Different products require different types of packaging. For example, fragile items need packaging that will protect them from breaking. On the other hand, products that are easy to break down or damage might do better in tamper-resistant packaging that you can reseal.

Common Uses of BOPP, OPP, and PP Bags

BOPP bags often are in packaging for food items like candy, nuts, and chips. They&#;re also common in the packaging of medical supplies and electronics. We&#;ve all seen the little white BOPP bags that pharmacies use to package pills.

OPP bags work well for packaging items like clothes, toys, and stationery. They&#;re also common in the food industry, especially for packaging frozen foods and baked goods.

PP bags commonly hold heavier items like books, magazines, and CDs. They&#;re also common in the packaging of medical supplies and electronics.

How To Spot the Difference Between BOPP, OPP, and PP Bags?

When looking at a bag, it can be challenging to determine what material it&#;s made from. Here are some tips to help you spot the difference between BOPP, OPP, and PP bags:

  • BOPP bags are usually thicker than OPP bags.
  • OPP bags are generally glossier than BOPP bags.
  • PP bags are usually more rigid than BOPP and OPP bags.
  • BOPP and OPP bags are generally transparent, while PP bags can be either transparent or opaque.

Of course, these are just general guidelines. The best way to be sure what type of bag you&#;re looking at is to check the label. The manufacturer should be able to tell you what type of material the bag contains.

When it comes to packaging your product, there is no one-size-fits-all answer. The type of bag you choose will depend on the needs of your product. So, take some time to consider what&#;s important to you and make a decision that&#;s best for your business.

With so many options on the market, it can be difficult to know which type of packaging is right for your product. But by understanding the difference between BOPP, OPP, and PP bags, you&#;re already well on your way to making an informed decision.

The difference between PE, PO, PP, PVC, OPP, CPE and ...

PE plastic bag is a polymer organic compound made by addition polymerization of ethylene. Polyethylene is recognized as the best food contact material in the world. Non-toxic, odorless, and odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, has the properties of moisture resistance, oxygen resistance, acid resistance, alkali resistance, general air tightness, excellent heat sealability and so on. It is one of the most widely used plastic bags and the most widely used plastic bags. The bag body is soft, but the transparency is not high enough for other materials, and it is relatively Mongolian. Good pull! Not easy to burst!


Hualei supply professional and honest service.

PO plastic bag is blow molded from high-density polyethylene (HDPE), non-toxic, feels like wax, has excellent low temperature resistance (minimum use temperature can reach -70 &#; -100 &#;), good chemical stability, can withstand large Corrosion of most acids and alkalis (not resistant to acids with oxidizing properties), insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation; but polyethylene is very sensitive to environmental stress (chemical and mechanical effects) and heat Poor aging. The properties of high-density polyethylene vary from species to species, depending on the molecular structure and density. Different production methods can be used to obtain products with different densities (0.91 &#; 0.96g / cm3). Polyethylene can be processed using general thermoplastic molding methods (see Plastic Processing). The body of the bag is brittle, the transparency is not high enough, it is even thicker than the PE material, it is a little white, and the pulling force is not very good.


PP plastic bag, commonly known as: 100% off plastic. Polypropylene is a representative of poly-α-olefin, a thermoplastic resin prepared by polymerization of propylene, and its monomer is propylene CH2 = CH-CH3. According to different initiators and polymerization processes, polypropylene can be divided into three configurations: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. Isotactic polypropylene is easy to form a crystalline state, with a crystallinity of more than 95% and a molecular weight between 80,000 and 150,000, giving him good heat resistance and solvent resistance; random polypropylene is an amorphous, White waxy material with slight stickiness, low molecular weight, -, irregular structure, lack of cohesion, less application The bag body is hard, but the transparency is relatively high, clear, the pull is not very good! Explosive!


PVC plastic bag, polyvinyl chloride, plus ingredients to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. The bag body is soft or hard, and can be ordered according to the needs of the customers. The transparency can also be based on the needs. Because there are super transparent materials, ordinary materials and frosted materials, the pulling force is good, and it is not easy to rip or burst. Mouth, because the two layers of material are together with the machine beer.


OPP plastic bags have the best transparency, the highest transparency, and the most translucent appearance. They have the functions of dust prevention and enhancing the value of the packaged products. The products inside can be fully displayed in sales, so OPP plastic bag products are usually used as outer packaging for commodity sales, which not only protects but also beautifies. Widely used in jewelry, jade, stationery, toys, tableware, kitchen utensils, clothing and other fields. The bag is the most brittle, with the highest transparency and insufficient tension, but it is the most explosive. And the printing is the easiest to discolor.


CPE plastic bags are the most commonly used plastic bags for electronic products, such as Ipad tablets, Iphone mobile phones, PSP handheld game consoles, etc. These plastic bags are matte and smooth on both sides. It can also provide more high-end and more luxurious packaging bags.
