Spray bag is a flexible packaging that integrates a plastic pouring port (usually a lid) into a sealed bag. It goes beyond standard vertical packaging bags and adds important functionality to liquid, viscous, or granular products.

Imagine it as a mixture of traditional bottles and flexible bags. The bag provides a lightweight and flexible body, while the nozzle provides controllable tilting and resealability of the rigid container.

The spray bag uses a combination of materials from the bag itself and the nozzle component.

These are multi-layer laminated boards, similar to other flexible packaging, selected according to the needs of the product.

Outer layer: Provides strength and printability.

• PET (polyester): tough, smooth, and durable.
• Biaxially oriented polypropylene (BOPP): transparent, glossy, and economically efficient.

Barrier layer: protects the product.

• Aluminum foil (AL): the ultimate barrier against oxygen, moisture, and light. It is crucial for sensitive products.
• VMPET (Metallized PET): Good gas and light barrier properties, softer than foil.
• EVOH (ethylene vinyl alcohol): an excellent oxygen barrier used in areas that require high transparency (foil free).

Sealing layer: The inner layer of the sealed bag, which is safe for product contact.

• PE (polyethylene) or CPP (cast polypropylene): Provides a strong heat seal and is chemically compatible with many products.
• RCPP (Steaming CPP): Used for products that require sterilization after packaging.

Nozzle: typically made of high-density polyethylene (HDPE) or polypropylene (PP). These materials have sufficient rigidity to be used as nozzles and can be heat sealed between bag layers during the manufacturing process.

Lid: Usually made of PP or polyethylene (PE). The cover can be a standard screw cover, flip cover, sports cover, or even a dispensing cover for precise measurement.

The film structure is customized according to the product. Here are typical examples:

For juice, water, and dairy products:

• Structure: PET/AL/PE
• Reason: Aluminum foil provides an absolute barrier for oxygen and light, preventing spoilage and maintaining flavor. PE is a safe and reliable sealant.

For distilled products (liquid soups, sauces, meals):

• Structure: PET/AL/RCPP
• Reason: The bag must be able to withstand high-pressure steam sterilization (distillation treatment). AL is the barrier, while RCPP is the only sealant that can survive at high temperatures.

Household and industrial liquids (detergents, oils, chemicals):

• Structure: PET/VMPET/PE or BOPP/VMPET/PE
• Reason: VMPET provides sufficient barriers to prevent moisture loss and aroma entry and exit. The structure is sturdy and resistant to chemical corrosion.

For high clarity products (such as high-quality beverages):

• Structure: PET/EVOH/PE
• Reason: EVOH provides a high oxygen barrier layer without an opaque aluminum layer, allowing consumers to see the product.

Due to its versatility, spray bags are widely used in various industries:

• Food and beverages: liquid eggs, milk substitutes, fruit juice, water, wine, cooking oil, syrup, baby food, liquid soup base, sauce.
• Home and personal care: washing powder, detergent, shampoo, conditioner, liquid soap, lotion.
• Industrial and automotive: engine oil, lubricants, chemicals, solvents.
• Pet care: liquid nutritional supplements, wet pet food ingredients.

• Excellent convenience: The nozzle allows for easy and controllable pouring and dispensing without the need for separate tools. The lid can be re closed to maintain the freshness of the product.
• Lightweight and space saving: They are much lighter than bottles and cans. When vacant, they occupy over 90% less space, reducing transportation and storage costs.
• Excellent product protection: The high barrier film can prevent oxygen, moisture, light, and pollutants, effectively extending the shelf life of the product.
• Reduce environmental impact: They use much less plastic than similar rigid bottles. Their lightweight properties also reduce the carbon footprint associated with transportation.
• Enhanced safety: For chemicals or oils, they are easier to dump and control than gravity type rigid containers, thereby reducing the risk of spillage.
• Brand and shelf impact: The large and flexible surface area serves as a vibrant graphic and marketing message billboard, making the product stand out.
• Suitable for users of all ages: features such as easy to grip sides and a simple lid make it accessible to both children and the elderly.

In summary, spray pockets are a highly evolved form of packaging that combines the protective properties of flexible films with the ease of distribution of rigid containers. It is an intelligent, efficient, and consumer friendly solution that is highly suitable for liquid and viscous products.
