What is an OPP Plastic Packing Bag?
OPP stands for oriented polypropylene. Similar to BOPP bags, OPP bags are strong and resistant to tearing and moisture. They also have high heat resistance, making them suitable for food products. However, OPP bags are more flexible than BOPP bags, making them easier to open.
Advantages of OPP Plastic Packing Bags
Widely Used in the Packaging Industry
Polypropylene derivatives like PP, OPP, and BOPP are resistant to organic solvents, acids, and alkalis. This makes them widely used in the packaging industry, where transportation and storage under changing atmospheres is unavoidable. Similar to cling films, they protect products from moisture and dust.
Customization
You can print your own logo and brand and customize bags in various specifications.
Environmental Benefits
OPP, BOPP, and PP materials are sustainable choices. They meet environmental requirements, are recyclable, and leave no carbon footprint in the manufacturing process.
OPP plastic bags: Everything You Need to Know!
OPP plastic can be described as shiny and clear plastic that is not stretchy. It is commonly used worldwide in the production of various plastic products. OPP stands for oriented polypropylene, which has high tensile strength and can withstand high temperatures.
How OPP Plastic is made?
This material is produced by melting high molecular weight polypropylene into a thin sheet through a narrow machine head. The material then proceeds through a dedicated stretching machine at a specific temperature and predefined speed.
The film can stretch in two vertical directions while being subjected to appropriate cooling or heat treatment. OPP plastic is tasteless and harmless with high impact strength. The properties of OPP film vary depending on the processing methods used.
The flat film method produces OPP plastic bags with a higher tensile ratio compared to the tubular film method. The extrusion and molding shaping technique commonly used in injection molding is also employed in the melting process of OPP. Sometimes, an antistatic additive is included to help the polypropylene surface resist dirt and dust.
OPP Plastic Features?
OPP plastic is resistant to acids, alkalis, and organic solvents. This makes it convenient for use in the packaging industry, protecting products from moisture.
OPP plastic performs outstandingly; it is anti-scratch and can withstand wear and tear. Its sealing properties are also excellent, making it suitable for use as gift bags or for packaging various food items such as bread, pastries, nuts, and spices.
OPP plastics are lightweight, which facilitates easy production and fast shipping, saving costs.
OPP plastic bags can also be customized according to customers' tastes and preferences.
Tips for safe plastic use
Plastic is ubiquitous and used in packaging our foods, beauty products, and health products.
It’s essential to know how to use plastics safely. According to doctors' recommendations, it is safer to heat food in glass or metal containers instead of plastic. Heating can increase the chances of chemicals leaching into your food from plastics.
Choose products marked BPA-free, like OPP plastic. Typically, you may find a leaf symbol on recyclable plastics indicating they are also BPA-free.
In conclusion, OPP plastic helps retailers and consumers preserve the freshness of food items throughout their shelf life. They provide stability in packaging, securing goods until they reach the end-user. Additionally, retailers can enjoy up to 50% reduction in glue usage compared to paper labels.
The production process is seamless and efficient, reducing waste due to fewer rejects. The aesthetic quality contributes to superior packaging appearance, maintaining an appealing look.
