White/Black Co-Extruded PE Bags

Description

In agricultural packaging, logistics and secure shipping, white/black co-extruded PE bags are a specialized solution that few alternatives can match. With over 40 years of experience in the plastics industry, Tashing (Di Dai Hung Co., Ltd.) manufactures high-quality co-ex poly bags with excellent mechanical strength, built to meet the requirements of both domestic customers and international importers.

What Is a White/Black Co-Extruded PE Bag?

A white/black co-extruded PE bag is a plastic bag produced by multi-layer co-extrusion blown film technology from virgin PE resin (LDPE/LLDPE). Its defining feature is two distinct colors on each side of the film, typically white/black or gray/black:

Exterior (white or gray): A smooth, glossy surface with strong ink adhesion, ideal for printing brand logos, product information and barcodes with sharp clarity.
Interior (black): Blocks light transmission, keeping the contents concealed and protected from sunlight exposure.

This dual-layer structure works as a double defense: the light exterior reflects sunlight and heat, while the black interior absorbs and blocks the remaining light.

Industrial Applications of White/Black Co-Extruded PE Bags

Logistics & E-Commerce Mailers

• Full privacy: The black inner layer makes the bag completely opaque, concealing the contents and details of high-value shipments.
• Tamper evidence: Each mailer can be fitted with a high-tack, tamper-evident adhesive strip. Once sealed, any attempt to open the bag distorts or tears the film, making tampering or product swapping easy to detect.

Coco Coir Grow ag for Export

• Product stability: Coco coir can lose quality, dry out or degrade under prolonged sunlight exposure. The co-ex film blocks light from reaching the product, helping preserve its moisture content and beneficial microbial activity during storage and long-haul ocean freight.

White/Black Co-Extruded PE Grow Bags (Nursery Bags)

• Optimal root protection: The white exterior reflects heat, keeping the growing medium cool and preventing root damage caused by heat absorbed from direct sunlight.
• Mimics natural soil conditions: The black interior creates a dark root zone, encouraging roots to grow quickly, stay healthy and anchor firmly in the growing medium, just as they would in natural soil.

Electronic Components & Industrial Machine Parts

• Protection against light-induced degradation: Suitable for FDI manufacturers packaging electronic components, precision machine parts or light-sensitive polymer materials. By blocking light, the bag helps reduce photochemical oxidation, preventing components from degrading or losing service life before assembly.

Weather-Resistant White/Black Co-Extruded PE Pallet Cover Bags

• Protection for outdoor storage: For palletized goods staged at seaports or open-air storage yards under intense sun, white/black co-extruded PE pallet cover bags act as a heat shield. The white exterior reflects solar heat, keeping temperatures inside the pallet from rising and helping prevent products from softening, deforming, or cartons from warping and weakening.
