Customized packaging for your need.
As we know, our living standards have been improving. As consumers, we will pursue fresher, healthier and safer vegetables and fruits. These vegetables and fruits may be supplied by local suppliers or from all over the world. Therefore, in order to ensure the freshness of vegetables and fruits, we will create temperature to delay their lifespan. Of course, the packaging bags for vegetables and fruits also play a very important role at this time. Today, let's take a look at the types of packaging bags for vegetables and fruits and what materials can be used for packaging.
The packaging bags for vegetables and fruits:
1. Plastic film bags or laminated packaging bags
They are usually made of polyethylene (PE) or polypropylene (PP), with transparent, lightweight, waterproof and other characteristics.
Do you know what is suitable for the kind of the packaging:
Tomatoes: Plastic film bags can provide certain protection, reduce external collisions and water loss.
Green peppers and colored peppers: can prevent surface damage and water loss.
Cucumbers: can maintain their freshness and crispness to a certain extent.
Bananas: can slow down the ripening of bananas. Citrus fruits such as oranges and tangerines: help prevent peel damage and water evaporation.
However, when using plastic film bags to package fruits and vegetables, be sure to choose food-grade bags and poke a few small holes appropriately to ensure a certain degree of air permeability to prevent fruits and vegetables from deteriorating due to lack of oxygen.
Laminated packaging bags: Made of multiple layers of different materials, they may have functions such as freshness preservation, moisture resistance, and UV protection.
Common types of laminated packaging bags are as follows:
Aluminum composite packaging bags: have good light-shielding and barrier properties, can effectively block the effects of light and oxygen on fruits and vegetables, and extend the shelf life.
Aluminum foil laminated packaging bags: the addition of aluminum foil greatly enhances the barrier properties of the packaging bag, and has significant waterproof, moisture-proof and oxygen-proof effects, which are suitable for fruits and vegetables with high requirements for freshness.
Co-extrusion composite packaging bags: For example, PA/PE co-extrusion bags, which combine the high strength of nylon (PA) and the good flexibility and sealing of polyethylene (PE), can effectively protect fruits and vegetables.
Multi-layer composite packaging bags: such as PET/PE/PA and other multi-layer materials, which combine the advantages of different materials and provide excellent freshness, pressure resistance and puncture resistance.
2.Paper bags: environmentally friendly and degradable, with good air permeability, can maintain the freshness of fruits and vegetables to a certain extent.
The following fruits and vegetables are more suitable for paper bag packaging:
Apples: Paper bags can provide a certain degree of protection and have good air permeability, which is conducive to the storage of apples.
Pears: It helps to keep the moisture of pears and prevent skin damage.
Peaches: It can reduce the impact of external factors on peaches and has good air permeability.
Strawberries: If it is a hard and not easily damaged strawberry variety, paper bags can provide a certain degree of protection and ensure air permeability.
Apricots: It can protect apricots to a certain extent and maintain good storage conditions.
When choosing paper bags to package fruits and vegetables, it is best to choose odorless and clean paper bags to ensure that the quality of fruits and vegetables is not affected.
3. Mesh bags: Generally used for fruits and vegetables that are larger or not easily damaged, such as watermelons, onions, etc., with good ventilation.
When using mesh bags for packaging, pay attention to the moderate size of the mesh to ensure that it can play a protective role and achieve good ventilation.
4. Vacuum packaging bags can effectively extend the shelf life of fruits and vegetables and reduce the impact of oxygen on fruits and vegetables.
These fruits and vegetables are more suitable for vacuum packaging bags:
Fresh corn: Vacuum packaging can effectively maintain the moisture and taste of corn and extend its shelf life.
Asparagus: Asparagus is easy to lose moisture, and vacuum packaging helps to maintain its freshness and crisp taste.
Broccoli: Broccoli can slow down oxidation and the loss of nutrients in a vacuum environment. Beans: Vacuum packaging can reduce the contact between beans and air and prevent them from deteriorating.
It should be noted that although vacuum packaging can extend the shelf life of fruits and vegetables, it is not suitable for all fruits and vegetables. For example, some fruits with soft skin and easy to be squeezed and damaged, such as strawberries and blueberries, are not suitable for vacuum packaging. In addition, fruits and vegetables after vacuum packaging also need to be stored at a suitable temperature to achieve the best preservation effect.
Customized bag types for vegetables and fruits
There are mainly the following types of customized bag types for fruits and vegetables:
1. Three-side sealed bag: This bag type has good sealing performance, simple structure and convenient use.
2. Self-supporting bag: There is a support structure at the bottom, which can be placed independently for easy display and storage.
3. Four-side sealed bag: All four sides are sealed, the packaging is firm, and the internal space is large.
4. Middle sealed bag: The bag is sealed in the middle and has a flat appearance.
5. Organ bag: The side is shaped like an accordion, with a folding structure, which increases the capacity of the bag.
6. Eight-side sealed bag: Strong three-dimensional sense, good display effect, and can carry more product information.
How to choose a suitable packaging bag for vegetables and fruits
When choosing packaging bags suitable for vegetables and fruits, we need to consider the characteristics of vegetables and fruits from several aspects:
1. Freshness requirements: If vegetables and fruits need to be kept fresh for a long time, packaging bags with good barrier properties should be selected, such as aluminum foil composite bags or bags with added preservatives.
2. Breathability: Some vegetables and fruits require a certain degree of breathability to prevent moisture accumulation and decay. Paper bags or plastic film bags with air holes may be more suitable.
3. Strength and puncture resistance: Avoid bag rupture during transportation and storage. For vegetables and fruits that are harder or have sharp parts, choose packaging bags with high strength and puncture resistance.
4. Size and shape: Choose the appropriate bag type and size according to the size and shape of vegetables and fruits to ensure tight packaging and reduce space waste.
5. Environmental protection: If you pay attention to environmental protection, you can give priority to biodegradable or recyclable packaging bags, such as paper bags or bags made of environmentally friendly plastic materials.
6. Cost: Consider your budget. The cost of packaging bags of different materials and types varies.
7. Printing and labeling: If used for sales, the packaging bags need to have clear printing and labeling to display product information and brand image.
8. Food safety: Make sure the selected packaging bags meet food safety standards and will not cause contamination to fruits and vegetables.
