Poly bags are made from a thicker layer of polyethene film
Poly bags are a versatile packaging solution used across industries, from food service and retail to e-commerce and healthcare. They are made from polyethylene, the most common type of plastic used globally, and offer lightweight durability and flexible sizing.
Poly bags are manufactured from a thicker layer of polyethene film, which can be customised based on the desired properties of the bag. For instance, a bag intended for carrying bricks would require a thicker film for added durability and puncture resistance. The thickness of polyethene film is typically measured in mils, with thinner bags (1-2 mil) suitable for lightweight items and thicker bags (3+ mil) designed for heavier or sharper objects.
The versatility of polyethylene allows for a range of poly bag types, each suited to shipping different goods. For example, LDPE (low-density polyethylene) is used in softer, more flexible bags, like produce bags at grocery stores. In contrast, HDPE (high-density polyethylene) is sturdier and is often used for bags carrying canned goods. Linear low-density polyethylene (LLDPE) falls somewhere in between, offering toughness and higher tensile strength, making it ideal for stretch films, toys, and certain flexible containers.
Beyond thickness and polyethylene type, poly bags can be customised further with different colours and properties. While the natural colour of polyethylene is somewhat translucent, poly bags can be opaque or transparent, depending on their intended use. For instance, polypropylene (PP) bags are known for their high clarity, showcasing their contents while protecting them from moisture, corrosion, vapours, chemicals, and organic solvents. This makes them ideal for the food industry, where consumers prefer to see products like dried fruit, nuts, candy, and confectionery.
In summary, poly bags made from a thicker layer of polyethylene film offer a versatile and durable packaging solution. By customising the thickness, polyethylene type, colour, and properties, businesses can create bags that meet their specific needs, whether for shipping fragile items, presenting products attractively, or ensuring food safety.

They are suitable for small, soft, and non-fragile items
Poly bags are suitable for small, soft, and non-fragile items. They are a popular choice for shipping small or lightweight items as they are lightweight and provide good protection for the contents during shipping. Poly bags are also used to bundle small items like screws, washers, and components without mess.
The use of poly bags for small items is especially common in industries like retail, e-commerce, and healthcare. For example, retailers and e-commerce companies often use custom-sized poly bags that match their product's dimensions, giving customers the impression of purchasing a high-quality item.
When using poly bags for small, soft, and non-fragile items, it's important to consider the weight and dimensions of the product. Thinner poly bags (1-2 mil) are suitable for lightweight items, while thicker bags (3+ mil) offer more durability and puncture resistance for heavier or sharper contents.
Additionally, poly bags are an excellent choice for situations where strength and leak prevention are crucial due to their thicker layer of polyethene film, making them more durable than plastic bags. They are also less prone to ripping or tearing when filled with fluids.

Poly bags are FDA- and USDA-compliant for food packaging
Poly bags are widely used in industries such as food service, retail, e-commerce, and healthcare. They are a versatile and cost-effective packaging solution, offering lightweight durability and flexible sizing. Importantly, poly bags can also be used for food packaging and are FDA- and USDA-compliant.
The FDA (U.S. Food and Drug Administration) has strict requirements for food-grade plastic packaging. Poly bags used for direct contact with food must meet these stringent standards to ensure customer safety. For example, food-grade bags cannot contain dyes or certain types of recycled plastics that may be harmful to humans.
Poly bags made from high-density polyethylene (HDPE) are a common choice for food packaging due to their excellent chemical resistance. This material is suitable for a wide range of food products and helps maintain the purity and integrity of the packaged goods. Conversely, low-density polyethylene (LDPE) is better suited for zipping plastic bags and applications requiring lower temperatures.
In addition to FDA compliance, some poly bags are also USDA-approved. These bags are typically made from 100% pure-virgin resin and offer excellent traceability for food safety. This dual certification ensures that food products packaged in these bags meet the highest standards for safety and quality.
When selecting poly bags for food packaging, it is crucial to work with reputable manufacturers and suppliers who understand the importance of compliance. By choosing FDA- and USDA-compliant poly bags, businesses can ensure that their products meet regulatory standards and provide a safe and high-quality experience for their customers.
