Clamshell blister packaging fruit tray

Types of clamshell blister packaging fruit trays

The clamshell blister packaging fruit trays are usually made of plastic and form a sealed container around the fruit. They are designed to protect delicate fruits such as berries and grapes from damage while in transit. There are different types of clamshell blister packaging fruit trays:

• Vacuum packaging clamshell trays:

  The air in the clamshell packaging is sucked out to make a vacuum. This stops fruits from getting stale or spoiling fast because of less oxygen. It also keeps fruits fresh by not allowing bacteria and fungi to grow without air. Even sensitive fruits that can easily spoil or get damaged last longer in a vacuum packaging clamshell tray.

• Modified atmosphere packaging (MAP) clamshell trays:

  This packaging puts a special gas mixture around fruits inside the tray. Unlike vacuum packing, MAP trays do not remove all the air. Instead, they change the kinds of gases in the air around the fruit. For example, trays may have more carbon dioxide and less oxygen. This gas mix keeps fruits from ripening too quickly, staying fresh longer. It works well for berries, tomatoes, and other fruits that need careful handling.

• Thermoformed packaging clamshell trays:

  Thermoforming is when plastics are shaped using heat. With this packaging, a big sheet of plastic is heated until soft. Then, machines shape the plastic into trays that fit fruits well. This makes sure the trays are strong but also have smooth curves inside for each fruit. So, thermoformed clamshell trays hold fruits firmly without squishing them. These sturdy trays protect delicate items and stack neatly for shipping.

• Injection molded packaging clamshell trays:

  Injection molding is another way to shape plastics. Here, liquid plastic is poured into molds to form the trays. This method makes very tough and long-lasting clamshell trays. They can withstand rough handling without breaking easily. Since injection molding creates precise shapes, the trays also fit fruits exactly. So, injection molded clamshell packaging works well for items needing strong protection on busy trucks or stores.

Design of clamshell blister packaging fruit trays

The design of the packaging fruit trays is critical to their functionality and visual appeal. Here are some key aspects of their design:

• Shape and Mold Design:

  The shapes of clamshell blister packaging trays are made using special molds. These molds are designed to fit the items perfectly. For fruits, this means creating spaces that keep the fruits from moving around too much. It helps prevent bruising or damage to delicate fruits. The trays can be flat or deep, depending on what needs to be packed.

• Material Selection:

  Clamshell packaging trays are usually made from materials like PET or PVC plastic. These materials are chosen because they are clear, so people can see what is inside, and also strong. The clear plastic used for clamshell packaging can be recycled in many places, which is better for the environment. It helps reduce waste compared to materials that can't be recycled. The materials also resist breaking easily, which is important for keeping fruits safe during delivery.

• Airtight Seal:

  The clamshell packaging trays make an airtight seal when closed. This helps keep the fruits fresh by preventing air from getting in or out. It is important for things like apples that can go bad if exposed to too much air. The tight seal also helps keep out water and dirt from outside, which could harm the fruits inside.

• Ventilation:

  Although the clamshell packaging trays are airtight, they also need to let air in some cases to avoid moisture buildup. Some trays have tiny holes or slots for ventilation. It is important for fruits that release gases when ripening, like bananas. Proper ventilation helps keep the fruits fresh longer.

• Easy Opening:

  While clamshell packaging trays are securely closed, they should also be able to open easily by consumers. If the packaging is too hard to open, people may get frustrated. Manufacturers want to ensure their trays can be opened without much effort so that customers can access the fruits inside quickly and easily. It is done by designing tabs or areas on the packaging where it can be pressed or pulled to break the seal safely.

Usage scenarios of clamshell blister packaging fruit tray

• Retail Packaging:

  Clamshell trays are commonly used for packaging and displaying fruits and vegetables in supermarkets and grocery stores. They provide protection during handling and shipping and allow customers to see the product clearly through the transparent packaging. The trays are often used for berries (e.g., strawberries, blueberries, raspberries, blackberries), mushrooms, cherry tomatoes, and other small or delicate fruits and vegetables.

• Shipping and Transportation:

  Clamshell blister packaging fruit trays protect produce during shipping and transportation. They are designed to withstand stacking and handling, reducing the risk of bruising, crushing, or damage to the enclosed items. Farmers, producers, and distributors use clamshell trays to ensure their products reach retailers and markets safely and in good condition.

• Fresh Cut Fruit and Vegetable Packs:

  Clamshell trays package fresh-cut fruits and vegetables, such as pre-sliced apples, salads, and melon cubes. They provide a convenient and hygienic option for consumers seeking ready-to-eat produce. Packaging companies offer trays that seal to maintain freshness and prevent contamination.

• Sustainable Packaging Solutions:

  With the growing demand for eco-friendly packaging, clamshell trays are also being produced from recycled materials or designed to be recyclable, compostable, or biodegradable. This allows for sustainable packaging solutions that reduce environmental impact and support the circular economy. Manufacturers and brands are exploring ways to produce clamshell trays that minimize plastic waste and pollution.

• Specialty and Organic Produce:

  Clamshell blister packaging fruit trays are used for specialty and organic fruits and vegetables. They often command a higher price and require packaging that reflects their premium quality. Clamshell trays provide a clean and appealing presentation for these products, helping to justify their higher cost and communicate their unique attributes to consumers.
