Transparent PET plastic sheet is an ideal material for thermoformed fruit and vegetable packaging boxes due to its excellent transparency, strength, plasticity and food safety.
Characteristics of transparent PET sheets
High transparency:
PET sheets have glass-like transparency, which can clearly show the appearance of fruits and vegetables and attract consumers’ attention.
Transparency helps to improve product display effects and increase purchasing desire.
Excellent mechanical properties:
PET sheets have high strength and toughness, and can withstand impact and pressure during transportation and stacking.
After thermoforming, the packaging box can maintain a stable shape and protect fruits and vegetables from damage.
Food safety:
PET materials comply with international food safety standards such as FDA and EU, and can directly contact food.
It is non-toxic and odorless, and will not affect the quality and taste of fruits and vegetables.
Recyclability:
PET is a recyclable material that conforms to environmental protection trends and helps reduce packaging waste.
Heat resistance and chemical resistance:
PET sheets have good heat resistance and are suitable for thermoforming processes.
Chemical resistance enables it to resist acidic substances released by fruits and vegetables and extend the life of packaging.
Advantages of Thermoformed Fruit and Vegetable Packaging Boxes
Customized Design:
Thermoforming technology can customize packaging boxes according to the shape and size of fruits and vegetables, providing better protection.
Air permeable holes or anti-fog coatings can be designed to extend the shelf life of fruits and vegetables.
Lightweight:
The packaging boxes made of PET sheets are light in weight, which reduces transportation costs and meets environmental protection requirements.
Extended shelf life:
Transparent PET packaging boxes can be combined with other preservation technologies (such as modified atmosphere packaging) to extend the shelf life of fruits and vegetables.
Good sealing can prevent moisture loss and external pollution.
Enhance brand image:
Transparent packaging boxes can clearly display the quality of fruits and vegetables and enhance consumer trust.
Brand logos or information can be printed on the packaging boxes to enhance brand recognition.
Application scenarios
Retail packaging:
Bulk or pre-packaged fruits and vegetables such as strawberries, blueberries, grapes, cherries, etc. are used in supermarkets and fruit and vegetable stores.
Transparent packaging boxes can attract consumers and increase product added value.
E-commerce packaging:
Applicable to the delivery of fruits and vegetables on e-commerce platforms, protecting fruits and vegetables from damage during transportation.
Lightweight design reduces logistics costs.
Gift packaging:
High-end fruits and vegetables (such as organic vegetables and imported fruits) can use transparent PET packaging boxes to enhance the quality of gifts.
Catering industry:
Used for fruit and vegetable display and storage in restaurants and hotels to keep the ingredients fresh.
Production process
Sheet extrusion:
PET resin is made into transparent sheets through extrusion process, and the thickness can be adjusted according to demand (usually 0.18mm-1.8mm).
Thermoforming:
The PET sheet is heated to a softened state and formed into the shape of a fruit and vegetable packaging box through a mold.
Thermoforming process is efficient and suitable for mass production.
Post-processing:
Post-processing such as cutting, trimming, and punching can be performed according to demand.
Anti-fog coating or printed patterns can be added.
Market trend
Sustainable development:
With the increase of environmental awareness, recyclable and degradable PET materials are becoming more and more popular.
Companies can improve their environmental image by using recycled PET materials.
Intelligent packaging:
Combined with smart labels (such as RFID or NFC tags), fruit and vegetable traceability and shelf life monitoring can be achieved.
Personalized design:
Consumers have an increasing demand for personalized packaging, and transparent PET packaging boxes can be customized to meet different market needs.
