Blueberry Punnet
StlPak manufactures clear PET and rPET blueberry punnets for retail, export and supermarket programs. Our range covers compact single-serve formats, standard retail packs, deeper containers and larger family-size packs, helping buyers match the right punnet to their target pack weight, berry size and sales channel. Our berry punnet range includes Blueberries Punnet, Strawberries Punnet, Raspberries Punnet, Blackberries Punnet, Cranberries Punnet, Gooseberries Punnet, Boysenberries Punnet, Loganberries Punnet and Mixed Berries Punnet for different fresh berry packaging needs.
A suitable blueberry punnet should do more than hold fruit. It needs to protect delicate berries during filling and transport, provide appropriate ventilation, maintain reliable closure performance and present the fruit clearly on the shelf. StlPak offers different container depths, ventilation layouts, closure designs and carton-loading options to support these requirements.
For branded retail programs, we can also support label areas, automatic labeling and printing solutions. Where an existing format is not suitable, selected projects can be evaluated for adjustments to container depth, material weight, ventilation holes or other structural details.
Whether you need a practical stock punnet for a standard blueberry program or a more tailored solution for your retail and logistics requirements, our team can help recommend suitable options and arrange samples for evaluation.

Right Blueberry Punnet Fit for Better Filling
A suitable blueberry punnet should hold the target pack weight properly without pressing the berries or making the pack look underfilled. The same 125g or 250g pack can require different container depths depending on berry diameter, fill height and headspace.
If the punnet is too shallow, berries may be squeezed when the lid closes or during carton stacking. If it is too deep, the pack may look loose or less attractive on the retail shelf.
StlPak helps customers choose suitable blueberry punnet sizes based on pack weight, berry size, container depth and sales channel, so the final pack looks full, protects the fruit and supports better retail presentation.
Ventilated Blueberry Punnets for Cooling and Transport
Blueberry packaging should support airflow without weakening the container. Ventilation holes, carton openings, stacking pattern and cold-chain conditions need to work together, especially for export, supermarket distribution and longer transport routes.
More holes do not always mean better performance. A suitable ventilation layout should help cooling air move through the pack while keeping enough strength for handling, carton loading and stacking.
StlPak offers different blueberry punnet structures with practical ventilation layouts, helping customers evaluate the right option based on pack weight, carton fit, cooling method and shipping distance.
Stock Molds, Labels and Custom Blueberry Punnet Options
A custom blueberry punnet project does not always require a new mold. In many cases, an existing punnet size can already meet the required pack weight, depth, closure and ventilation needs.
For retail programs, StlPak can also support label areas, automatic labeling and printing solutions, helping brands add logos, barcodes, product information and market-specific packaging details without changing the main container structure.
When existing molds cannot meet the required size, depth, hole pattern or label area, StlPak can also evaluate custom development based on the project quantity and technical requirements.
Blueberry Punnet Sample Support Before Bulk Orders
Choosing a blueberry punnet only from a catalog is not enough. The sample should be checked with real blueberries, target pack weight, carton layout and stacking conditions before confirming the final packaging.
To recommend suitable samples, StlPak usually reviews your target pack weight, average berry size, carton size, packs per carton, sales market, transport route and labeling requirements.
This helps customers avoid unnecessary mold costs, reduce trial time and test blueberry punnets that are closer to their real retail or export packing needs.
How to Choose the Right Blueberry Punnet
Choosing a blueberry punnet is not only about checking the outside dimensions in a specification table. Buyers should also compare usable depth, lid clearance, closure style, ventilation position, carton loading and how the filled pack will look on the retail shelf.
A shallow punnet may look neat but can press the berries when the lid closes. A deeper punnet may give more space, but it can make the pack look underfilled if the berry size or target weight does not match. Closure design and sidewall strength also affect stacking, handling and transport performance.
StlPak helps buyers compare existing PET and rPET blueberry punnet models by real packing use, not only by catalog size. This makes it easier to narrow down suitable options before requesting samples or confirming a bulk order.
Blueberry Punnet Details Display
For most retail and export programs, a clear ventilated clamshell made from food-grade PET or rPET is a practical choice for fresh blueberries. The right packaging should protect the berries from crushing, allow suitable airflow, support stacking, and present the fruit clearly on the retail shelf. StlPak helps buyers select a suitable clamshell based on pack weight, berry size, sales channel, and transport distance.
StlPak blueberry clamshells can support common retail pack weights such as 125g, 170g, 250g, 500g, and 1 lb. The right container should be selected based on net weight, blueberry size, fill height, headspace, sales market, and transport requirements. Share your target pack weight and approximate berry diameter, and StlPak can recommend a suitable existing mold or custom solution.
Blueberries generally benefit from suitable ventilation, but the hole pattern should match the packaging format and logistics conditions. Side, bottom, and top holes can each support airflow in different ways, while excessive openings may reduce container strength. StlPak can help evaluate the appropriate ventilation layout based on pack weight, stacking requirements, and shipping distance.
PET and rPET are widely used for blueberry packaging because they provide good clarity, rigidity, lightweight protection, and retail visibility. PET and rPET packaging may be recyclable where appropriate collection and recycling systems are available. StlPak can offer food-grade PET or recycled PET options according to your market and sustainability requirements.
Yes. StlPak currently offers more than 10 existing blueberry clamshell container options, covering different pack weights, container depths, ventilation designs, and label areas. These ready-to-use options can help buyers reduce development time, lower initial mold investment, and quickly evaluate suitable packaging for retail or export programs. Samples can be arranged for testing and evaluation. For projects that require special sizes, structures, hole patterns, or label areas, StlPak can also support custom development. Suitable prototype or sample development may be arranged in around 7 days after design confirmation, depending on the project requirements.
Yes. StlPak can support private-label blueberry packaging with custom label areas, automatic labeling services, and printing solutions for suitable projects. In addition to label application, StlPak can also provide offset printing with up to 8 colors, helping brands present logos, product information, and retail graphics more professionally. These options help growers, packers, distributors, and retailers improve shelf recognition and brand presentation without necessarily developing a completely new packaging mold. The suitable labeling or printing solution depends on the selected container design, artwork requirements, order quantity, and production feasibility.
Yes. Depending on the project, StlPak can support adjustments to container depth, material weight, ventilation holes, label areas, and other structural details. Some requirements can be handled through existing molds, while major size or structural changes may require a new mold.
In many cases, different StlPak blueberry packaging sizes can be combined in one container order, subject to MOQ, carton quantities, and production scheduling. Share your required sizes and estimated quantities, and our team will help assess the most practical loading and ordering plan.
