Our calibration may not meet all calibration requirements for critical packaging machines, be sure to evaluate our calibration process by contacting our engineering group at 800-550-3854. Your machine’s calibration status is a matter of record when leaving our laboratory, the data-logging session represents the “as left” condition of your sealer at the time of calibration. It is possible that a mechanical/physical change, i.e. shipping damage, could change your calibration, we therefore recommend evaluating your machines thermal performance when your sealer returns in order to thwart possible seal failures. Please contact our engineering group for guidance on appropriate protocols and testing equipment to perform a calibration check at 800-550-3854. Calibration can be altered if certain parts are changed on the sealer, it is recommended that you always check the thermal performance after service or repair of your sealer. Some of the sealers we calibrate have a wide +/- thermal performance range, therefore when developing your packaging validation you should allow for that range in order to understand the sealers possible range of performance after calibration. Because many factors can affect the adherence to the calibration range we always recommend checking calibration throughout the year.
Temperature sampled at a single location on the platen at a single set point. A redundant data logging session is performed with a different meter and test lead to verify test accuracy. This includes certificate, machine affixed sticker with record number, technicians name, and calibration due date. The line item data, as well as waveform data, is also included with this calibration package. It is the customer’s responsibility to understand the appropriate calibration needed. We do not asses the value of the “type” of calibration selected to the regulatory process that our customers are bound.

Before returning your packaging equipment for service or calibration, please read the following SRA (Service Return Authorization): Third party shipping organizations such as UPS and Federal Express are accustomed to moving a variety of packages, but oftentimes they disregard fragile labels. The handling typically with these types of carriers is very rough. Within our own shipping department we have a dock height drop arbiter to determine how well a machine is packed. In other words, if your product were dropped at the height of a commercial truck dock, it should survive the fall unscathed. In order to achieve this robust packaging, you should not use fillers such as loose filled Styrofoam, as it allows too much movement within the container during the shipping process.
When preparing your sealing equipment for shipment, you should first secure the sealing jaws by carefully placing a foam rubber or corrugated insert in the jaws in order to prevent the jaws from moving during shipment, which can cause a sealing jaw breakage. After securing the jaw, the sealing equipment should be placed in an oversized plastic bag in order to prevent packaging material and particulates from entering the inside of the machine during the shipping process. The bagged machine should be placed in a heavy, preferably double walled, corrugated box with a minimum of six inches of buffer space between the machine and the box walls. This includes the bottom of the box as well. A foam sheet should be placed on the bottom of the box. The sealing machine should be placed in the center and all sides surrounding the machine should also be buffered with multiple layers of corrugated or foam material. Pay special attention to the jaw ends where the electrodes are located. This process should be repeated for the top of the machine. There should be no air space on any of the sides within the box, so the machine cannot move during shipment.
Also, if you are sending any loose parts with the machine, such as cables, etc. do not place them near the machine as they may rub during shipment causing damage. Do not send the machine table (that the pouch rests on when sealing) as this may rub against the machine and cause damage. If you have any specific requests in terms of how the machine should be calibrated or serviced, or a description of the problems the machine is experiencing, those should be included with the documentation. Also, prominently note any safety concerns or specific hazardous conditions of the sealer under the Additional Comments section of the SRA Number Request Form.
A Maintenance Supervisor’s name and phone number should be included. The machine should be strapped with fiber strapping tape or nylon shipping straps and marked excessively with red fragile labels on every exposed panel of the shipping container. Further, the SRA (Service Return Authorization) number should be prominently marked on the face of the box. Also, it has been our experience even when utilizing extreme caution, machine damage can still occur. Therefore, it is vital that you send the equipment insured for the purchase amount of the unit in order to secure your investment. Van der Stähl Scientific Inc. cannot be responsible for any equipment in transit to our facility for service and repair.

VDS makes no claims that our medical device packaging equipment meets the requirements of all medical device manufacturers’ validations. Medical device packaging validation varies greatly depending on the risk policy of the medical device manufacturer as well as the class of medical device. It’s important that our customers understand all of our packaging machine functionality in terms of accuracy of the sealer, machine alarms as well as other negative machine attributes that might affect your medical device packaging validation. It is the customer’s responsibility to maintain the equipment in order for the machine to develop expected performance.
Due to the wide range of packaging materials and throughput it is impossible to develop a generic recommended preventative maintenance plan. It is the customer’s responsibility to develop a preventative maintenance plan based on machine settings and throughput. It is the customer’s responsibility to calibrate the machinery, our firm does not send out reminders or notifications regarding calibration or maintenance. VDS does not perform validations for our customers as is beyond the scope of our function as machine provider. The process of medical device packaging validation is complicated and should be performed by quality or manufacturing engineers that understand the installation qualification process before purchasing packaging equipment.
We’ve received your submission and will be in touch soon.
Please carefully read and agree to the test methods that we utilize for medical pouch testing. It is important to remember that we do not interpret the data as to its value to your process as this function should be determined by your quality team against your packaging validation plan. Again it is vital that you read and understand the limits of our medical pouch study and to make sure that our procedures meet your regulatory and internal quality requirements. Please note that these factors may not all be applicable to your particular material.
We only provide raw data to be analyzed by your quality team
Any special requirements must be in writing on our submission form
We cannot perform any test procedures that falls outside our scope of accreditation
We do not perform statistical analysis of your study
We do not perform DOE’s (design of experiments)
1. Ensure that the number of samples that you are sending is sufficient to perform the tests. Remember that some of the material may be sacrificed during the process of determining the upper and lower limits of the material.
2. For every different type of material, or different size of pouch, an individual form must be filled out with the required information so that the test report can be completed properly.
3. Our test method is the following method as stated in the ASTM F88/F88M-15:
4.2.1 Technique A: Unsupported — Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.
4. Seal your pouch samples or gather samples from production that you wish to have evaluated. Be sure to note the sealing machines serial number that created the samples. If you require pouch normalization periods longer than our standard 48 hours, please indicate your normalization dwell preferences.
5. Provide us with adequate seal samples (35 for our standard test program) as well as additional buffer samples. If you are sending samples sealed at various times and temperatures settings, please mark specimens individually to thwart confusion. Please indicate any special conditions on this form.
6. Be sure to read our peel study SOP and disclaimer to be certain that our testing methodologies are in sync with your regulatory and internal requirements. Send in sturdy box to our Laboratory.
This test method covers the measurement of seal strength in flexible barrier material, in this case medical device pouches (F88 1.1). This test method measures the force required to separate one side of a fin type seal from the other and also identifies the method of seal failure (F88 1.4).
Significance and Use: In accordance with section four of the ASTM F88/F88M:
The measurement of seal strength is important not only in determining opening force but also determining the ability of the process to produce consistent seals (F88 4.1). While measuring the opening force is important there are times when the force may need to be lessened to facilitate opening (F88 4.1). Besides maximum force the average force to open the seal may be useful for some applications and in those cases should be reported (F88 4.1.1). Because some of the force measured may be caused by other influences beside seal strength it is important to use only one technique throughout a set of tests (F88 4.2). We have standardized our usage to the following: Technique A: Unsupported—Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted (F88 4.2.1).
Apparatus: In accordance with section six of the ASTM F88/F88M:
We use a PTT-100V test unit that has a system for measuring the force required to separate the sample and the rate of jaw separation, these systems are accurate to +/-2% (F88 6.1) This sealer utilizes a constant rate of separation that is adjustable from 200 – 300 mm/min and has lever action grooved jaws to prevent slippage of the specimen during testing (F88 6.1).
We use either an SPC-1 or SPC-2 specimen cutter to create a sample with a size of 1.00 in. [25.4 mm] in width within a tolerance of +/-0.5 % (F88 6.2, Test Methods D882: 5.4).
In accordance with section seven of the ASTM F88/F88M the sample population should be of sufficient size to determine overall performance of the seal and sealing system (F88 7.1). Indiscriminate removal of samples with defects may bias the results and should be considered carefully depending on the purpose of the investigation (F88 7.2).
Aging and Conditioning:
In accordance with section eight of the ASTM F88/F88M a minimum of forty hours shall be allowed for conditioning of any samples received, unless otherwise requested by the customer or if other information shows that seal strength stability is reached in a shorter time (F88 8.1, 8.2). The conditioning period may be shortened if necessary to meet certain test objectives, such as the testing of seal strength after a specific period of storage (F88 8.3).
Procedure: In accordance with section nine of the ASTM F88/F88M:
The test unit is calibrated per the manufacturer’s specification (F88 9.1). The specimens are cut to size following the guidelines in section 9.2, making allowances where it is permitted due to smaller grip separation (F88 9.2). Ensuring that only Technique A: Unsupported is used to minimize variance, each leg of the specimen is fixed into the grips with the sealed area being placed an equal distance between the grips (F88 9.3). Center the specimen in the grips, aligned so the seal line is perpendicular to the direction of pull, making sure no stress is put on the specimen prior to the test (F88 9.4). Please note on the test report the orientation of the fin seal as a significant difference has been measured based upon orientation (F88 9.5) If the specimen peels apart in the seal area, either by adhesive failure, cohesive failure, or delamination, the average peel force is measured by the testing machine as a part of the test cycle (F88 9.8, 9.8.1). If the specimen does not peel significantly in the seal area and failure is largely by breaking, tearing, or elongation of the substrate material, average force to failure may have little significance in describing seal performance (F88 9.8.2).
