Distinguishing single film packaging and laminated film packaging

There are many applications from single film packaging and laminated film packaging in life. But many customers still do not understand each of these types of packaging.

1. What is single film packaging?

Single film packaging is made out of a “film,” or a thin flexible sheet of plastic. Plastic film is typically defined as any plastic less than 10 mils thick. The majority of plastic films are made from polyethylene resin and are readily recyclable if the material is clean and dry.

The resin coding system was originally intended for rigid plastic containers only. However, many manufacturers put the code on plastic films too. If no resin code is printed on the plastic film or bag, the film’s application may indicate the resin type since different resins are chosen for their unique performance or observe the film’s characteristics and appearance and compare to the descriptions below.

LDPE – LOW-DENSITY POLYETHYLENE

Resin Code #4

Characteristics and Examples:

Unpigmented films have high clarity, moderate stretch, and strength characteristics.

• Bags (e.g., thicker newspaper bags, bread bags)
• Bubble wrap (may also contain nylon)

Note: Bubble wrap recycling can be difficult without local markets due to shipping constraints.

LLDPE – LINEAR LOW-DENSITY POLYETHYLENE

Resin Code #4

Characteristics and Examples

• Unpigmented films have moderate clarity, slightly tacky feel to the touch.
• Bags (e.g., clear, thin newspaper bags)
• Dry cleaning film

MDPE – MEDIUM DENSITY POLYETHYLENE

Resin Code #4

Characteristics and Examples

• Unpigmented films have moderate clarity, poor stretch, and strength characteristics.
• Consumer paper packaging (e.g., toilet paper, paper towel)

Note: MDPE is a variation in the production of LDPE and is often labeled #4. It’s generally used as an alternative to other resins in film applications where strength is not required.

HDPE – HIGH-DENSITY POLYETHYLENE

Resin Code #2

Characteristics and Examples

• Unpigmented films have some opacity, crinkle to the touch, low stretch, high strength, and can tear easily.
• Most grocery bags
• T-shirt bags
• Bags with sealed air for packaging (e.g., air cushions)

Note: Release air from air cushions before including with bags.

2. What is laminated film packaging?

Our laminated packaging covers a wide range of industries: from food & beverages to technical applications, from agriculture to healthcare, and from pet food to beyond. Our laminated film packaging is delivered in rolls or as complete bags. As for the rolls, after delivery, they are formed on the customer’s machine. This requires you to have a product packaging machine. If you do not have this type of machine, choose from our complete bags.

Our laminated films can be used by both horizontal and vertical Form Fill Seal machines. And with rotogravure prints, we offer multi-color solutions that can tackle even the most challenging of designs.

Feature

• Excellent controllability,
• High bond strength
• Can be applied to products processed in the microwave oven
• Customizable.
