100um LDPE Bags 12 x 18″ / 455 x 305mm (500 per Carton)

Our 100um LDPE Bags 455 x 305mm provide a strong, wide-format packaging option for products that need extra space together with the durability of a heavy-gauge poly bag.

Made from industrial-grade LDPE, these transparent bags combine a robust 100 micron thickness with the flexibility and clarity that make polyethylene suitable for a broad range of commercial packaging applications.

The clear film allows contents to remain easily visible for product identification, stock management and presentation, while the LDPE material helps create an effective barrier against everyday moisture and dust.

Measuring 455 x 305mm (approximately 18 x 12″), the broad rectangular profile is useful for food products, folded apparel, textiles, hardware, components, retail merchandise and other items where additional width is required.

Each bag features a bottom-sealed construction for added durability and is supplied open at the top. When a secure enclosed package is preferred, the opening can be closed using a compatible heat sealer.

Heavy-Duty 100 Micron LDPE

At 100 micron thickness, these bags provide significantly more material strength than standard lightweight LDPE packaging.

The heavier gauge makes them particularly useful for products requiring a stronger and more substantial flexible bag, including items that may experience frequent handling during storage, packing or distribution.

Despite the thickness, LDPE retains flexibility, allowing the packaging to conform around products of varying shapes.

Wide Format for Broader Products

The 455mm width and 305mm length create a broad rectangular shape that is particularly useful when a product requires more width rather than additional bag length.

This format can suit larger food items, bakery products, folded apparel, textiles, components and retail merchandise that may be awkward to package in narrower bags.

Clear Visibility with Practical Protection

Transparent LDPE keeps packaged products clearly visible, making stock identification, warehouse organisation and product selection easier.

The polyethylene film also helps provide an effective barrier against dust and moisture, reducing everyday environmental exposure during handling and storage.

Durable Bottom-Sealed Construction

Each bag features a secure bottom seal, providing a dependable base for packaged contents.

Combined with the heavy 100um film, this construction provides a robust flexible packaging solution for suitable food, retail and industrial products.

Suitable for Heat Sealing

These bags are supplied open and can be closed using an appropriate impulse heat sealer.

Heat sealing provides a clean and secure finish, making the bags useful for products being prepared for food packaging, retail presentation, storage, transport or distribution.

Why Choose 100um LDPE Bags?

When wider products need heavy-duty flexible packaging, these 455 x 305mm LDPE bags provide a practical alternative to thinner or narrower poly bags.

Their combination of 100 micron material strength, broad dimensions, excellent visibility, bottom-sealed construction and heat-sealing capability makes them suitable for a wide range of demanding commercial applications.
