Bürkle Packaging Bags with Closure are clear, resealable LDPE bags designed for the storage, collection, protection and transport of specimens, samples and packaged products.
Manufactured from crystal-clear low-density polyethylene (LDPE), the bags use a simple push-lock / zipper-style closure that can be opened and resealed during routine handling. The transparent film allows contents to be visually inspected without opening the bag.
Bürkle specifies a uniform 0.05 mm / 0.002 in. film thickness across the entire 2348 series. The film is waterproof, has good tear resistance and helps keep contents protected from dust during storage and handling.
Available in ten sizes from approximately 80 mL to 6500 mL, every size is supplied in a pack of 100 bags.

Bürkle designed the 2348 series for the storage, collection, protection and shipping of specimens, samples and packaged products.
Typical uses can include:
The Bürkle 2348 series is manufactured from crystal-clear low-density polyethylene (LDPE).
Transparent construction allows operators to visually identify the contents, approximate quantity and general condition of a sample without opening the bag.
This is useful in laboratories and production environments where several samples or retained products are stored together and rapid visual identification is important.
Every size in the Bürkle packaging-bag family uses approximately 0.05 mm / 0.002 in. film.
Bürkle describes the film as having good tear resistance, making it appropriate for routine handling, storage and movement of suitable specimens and materials.
The consistent film thickness means customers can select the bag based primarily on required dimensions and sample volume rather than having different material thicknesses between capacities.
The bag uses a push-lock closure, commonly described as a zipper-style resealable closure.
This allows the bag to be opened and resealed during normal use without requiring heat sealing or separate clips.
Push-lock bags are especially convenient for applications where samples, components or materials need to be accessed more than once during storage or testing.
Bürkle describes the LDPE film as waterproof and states that contents remain protected from dust when the bag is closed.
This provides useful protection during routine laboratory storage, sample organization and transportation.
Bürkle describes the film itself as waterproof, but the standard 2348 packaging bag should not automatically be treated as a sterile, validated liquid-tight or leakproof sampling container. For microbiological sampling, liquid samples or applications requiring a sterile or specialized leak-resistant closure, use a purpose-designed sampling bag.
Bürkle publishes food-contact compliance documentation covering the 2348 packaging-bag series.
This makes the bags relevant for suitable food and beverage applications such as:
Facilities should still verify that the bag, sample type and intended use meet their specific food-safety, sanitation, allergen-control and quality requirements.
The combination of clear construction, resealable closure and multiple sizes makes these bags practical for routine food-production quality-control work.
Potential applications include:
If the sample will be submitted for microbiological analysis where sterility is required, select a sterile sampling bag instead.
Bürkle packaging bags can be useful for general laboratory organization and sample handling when a sterile container is not required.
Typical applications may include:
Industrial laboratories and manufacturing QA/QC departments can use the bags for suitable materials such as:
The lightweight bags can also be used for suitable non-sterile field and environmental sample-handling applications.
Their flat format takes up little space in a sampling kit and allows unused bags to be carried efficiently.
For analytical work, always confirm that LDPE and the non-sterile push-lock format are appropriate for the material and analytes being collected.
Bürkle specifies the standard 2348 packaging bags as without a dedicated labelling field.
Identification can instead be applied using a suitable external label or marker system compatible with the LDPE surface.
If a permanently printed write-on panel, sample number or chain-of-custody feature is required, choose a purpose-designed sample bag with those features.
Bürkle offers a 25 mm sampling-bag clamp that can hold compatible bags open during sampling.
The clamp can be used with sampling equipment such as Bürkle StickProof or PowderProof devices, allowing liquids or powders to be transferred into a bag without the operator needing to hold the bag directly.
This can improve convenience and help reduce unnecessary contact with the bag opening during suitable sampling procedures.

The Bürkle 2348 packaging bags are manufactured from crystal-clear low-density polyethylene, commonly abbreviated LDPE.
Bürkle specifies a film thickness of 0.05 mm, approximately 0.002 in., across all sizes.
Each Bürkle 2348 variant is supplied as a pack of 100 bags.
Yes. The bags use a push-lock or zipper-style closure that can be opened and resealed during normal use.
Bürkle describes the LDPE film as waterproof. This should not be confused with a validated liquid-tight or leakproof sampling-bag specification.
No sterile claim is published by Bürkle for the standard 2348 packaging-bag series. If a microbiological or sterile sampling procedure requires a sterile bag, use a product specifically supplied and documented as sterile.
Bürkle publishes food-contact compliance documentation for the 2348 series. Facilities should still confirm that the bag and intended application meet their specific food-safety and quality requirements.
Yes. They are well suited to storing or transporting suitable powders, granules and other dry samples where a resealable bag is useful.
The film itself is waterproof, but Bürkle does not describe the standard 2348 series as a sterile or validated leakproof liquid-sampling system. For free liquids where leakage prevention is critical, select a purpose-designed liquid sample bag or container.
No. Bürkle specifies the 2348 packaging bags as having no dedicated labelling field. A suitable external label or compatible marker can be used when identification is required.
Cambridge offers ten sizes ranging from approximately 80 mL to 6500 mL, with dimensions from 100 × 70 mm up to 400 × 300 mm.
They can be considered for suitable non-sterile food-contact and retained-sample applications. Microbiology samples that require sterile collection should use a sterile sampling bag instead.
The Bürkle packaging bag is a general-purpose resealable LDPE bag for storage, packaging and sample handling. A sterile sampling bag is manufactured and packaged specifically to maintain sterility for contamination-sensitive or microbiological sampling applications.
Cambridge Environmental Products supplies Bürkle LDPE packaging and sample bags in Canada for food and beverage QA/QC, laboratory, environmental, industrial and research applications.
Cambridge Environmental Products supplies Bürkle bags, bottles, containers and sampling equipment across Canada.
If you are unsure whether a general packaging bag or a sterile sampling bag is appropriate, send us your sample type, approximate volume, whether food contact is required, whether the sample contains liquid and whether sterility or tamper evidence is required.
General packaging bags, sterile sampling bags and tamper-evident sample bags serve different purposes. The right choice depends on the sample, sterility requirements, closure type and laboratory method.
Send Cambridge your application and we can help identify the appropriate Bürkle or laboratory sampling bag.
