Custom printed resealable plastic bags (typically referring to bags with zippers or other sealing devices) are a very popular packaging method. They are convenient and environmentally friendly, suitable for the packaging of various food and non-food products. For the customization of such packaging bags, the following key factors need to be considered:
The material of resealable bags directly affects their performance and environmental friendliness. Common materials include:
Polyethylene (PE): A common plastic material with good sealing properties and durability.
Polypropylene (PP): Has better tensile strength and transparency, suitable for food packaging.
Low-Density Polyethylene (LDPE): Flexible and suitable for making resealable bags.
High-Density Polyethylene (HDPE): More durable and stronger than LDPE, suitable for packaging requiring high tear resistance.
Composite Materials: For example, PE combined with an aluminum foil layer can enhance moisture, oxidation resistance, and durability of the bag.
Biodegradable Plastics: Such as PLA (Polylactic Acid) and PBAT. These materials are more environmentally friendly and provide higher compostability for resealable bags.
The design of resealable bags usually includes the following aspects:
Sealing Method: The most common sealing method is the zipper seal, which can easily open and close the bag, keeping food dry and fresh. Other sealing methods include strip seals (sealing by inserting a strip device).
Size and Capacity: Custom sizes and capacities according to usage needs. Common sizes include small packages (such as 50g-100g) and large packages (such as 500g-1000g), which can be adjusted based on brand requirements.
Convenience Design: Bags can be customized with easy-tear designs for easy opening by consumers, or with handle hole designs for easy carrying.
Single-Sided or Double-Sided Printing: Depending on the need, choose single-sided or double-sided printing to maximize the use of bag space to display brand information, product information, and pattern designs.
Digital Printing Technology: A printing process that goes directly from electronic files to print media without using plates or molds found in traditional printing. Compared to traditional printing, digital printing has higher flexibility, shorter production cycles, and lower costs (especially in small batch production).
Eco-Friendly Inks: Choosing eco-friendly water-based inks or plant-based inks for custom printing is crucial, as it reduces environmental pollution and enhances product eco-friendliness.
Moisture Resistance: For food packaging, consider using materials with moisture and oxygen barrier functions, such as aluminum foil composite bags. They can effectively extend the shelf life of food.
Breathability: Some foods (such as fresh fruits and vegetables) may require breathable packaging, which can be customized with micro-perforated designs.
UV Resistance: Some foods, such as coffee and nuts, are very sensitive to light and may require UV-resistant packaging bags.
High Temperature or Freezing Resistance: If the food needs to be stored in freezing or heating environments, custom bags suitable for cold chain transport with low temperature or high temperature resistance are recommended.
With the increasing awareness of environmental protection, more brands are choosing to use recyclable or biodegradable materials for custom packaging bags. If you have high environmental protection requirements, consider:
Fully Biodegradable Bags: Bags made of fully biodegradable plastic materials (such as PLA, PBAT) decompose in suitable compost environments, reducing environmental pollution.
Recyclable Plastic Bags: Made of recyclable polyethylene or polypropylene materials, allowing consumers to recycle and reuse the bags.
Production Cycle: The production cycle for custom printed resealable bags is generally 2-4 weeks, depending on the complexity of the design, printing method, and production volume. For urgent products, you can discuss expedited production with the manufacturer.
Order Quantity: Generally, custom printed products have a high minimum order quantity, usually requiring thousands or more units. If your demand is relatively small, you can look for manufacturers that specialize in small batch custom orders.
The price is often affected by the chosen materials, the complexity of the printing design, bag size, and order quantity. Custom printed bags will have a more favorable unit price for larger quantities, but if it's a small batch customization, the unit price may be higher.
