How To Choose The Packaging Film
When choosing a packaging film, there are several factors to consider to ensure that the selected packaging film can meet the protection, display and storage needs of the product. Here are some key selection criteria:
1. Material Type
● Polyethylene (PE): Commonly used in food packaging, with good moisture resistance and flexibility.
● Polypropylene (PP): High transparency, suitable for displaying products, good heat resistance, suitable for microwave heating.
● Polyester (POF): high strength, good temperature resistance, suitable for long-term storage.
● Aluminum foil: has excellent barrier properties and is suitable for products that are sensitive to light and oxygen.
2. Thickness
The thickness of the packaging film directly affects its strength and protective performance. Generally speaking, the thicker the thickness, the better the protective performance, but it will also increase the cost and weight.
3. Breath-ability
For some foods, proper air permeability can extend the shelf life. Choosing packaging films with appropriate air permeability can effectively prevent mold and rot.
4. Moisture resistance
If the product is sensitive to humidity, it is important to choose a packaging film with good moisture barrier properties. Polyethylene and aluminum foil usually have good moisture barrier properties.
5. Transparency
Transparency is an important factor for packaging that needs to showcase products. Highly transparent packaging films can enhance the visual appeal of products.
6. Printing performance
If you need to print brand logo or product information on the packaging film, it is very important to choose the right material for printing. The surface treatment of some materials can improve the printing effect.
7. Environmental
With the improvement of environmental awareness, choosing biodegradable or recyclable packaging films has become more and more important. Understanding the environmental characteristics of materials can help companies enhance their brand image.
8. Cost
Choose the right packaging film according to your budget. The prices of packaging films of different materials and thicknesses vary greatly, so you need to consider the cost-effectiveness comprehensively.
9. Purpose
Choose the right packaging film based on the characteristics and purpose of the product. For example, fragile items require thicker protective films, while food requires materials that meet food safety standards.
10. Supplier Selection
Choose a reputable supplier to ensure the quality and service of the packaging film you purchase. You can evaluate the reliability of the supplier by checking customer reviews and cases.
Summarize
Choosing the right packaging film is an important part of ensuring product safety, extending shelf life and improving market competitiveness. By comprehensively considering factors such as material type, thickness, air permeability, moisture resistance, transparency, printing performance, environmental protection, cost, purpose and supplier, you can find the packaging film that best suits your product.
